Over the years, I've collected a lot of data on women from dating, conversations, and being in Swinger circles. Among the most interesting is the difference between women that are good at sex, versus women who are bad at it. It's a very difficult situation for many men to meet a very pretty woman, that is horrible at sex, and try to teach her or make corrections. Here is a list of characteristics that women that are bad at sex often have: 1) The opinion or arrogant attitude that being naked and laying there is enough, aka 'dead fish' Women like this often need to get a clue and perhaps need to watch some porn. Often they don't have any idea about how to do sex, thus they lay down and play dead. They can think they are being "good girls", when in fact they are just plain bad. 2) Unwillingness to try anything new sexually This is sadly too common. What is even weirder, you can suggest to certain women to try something new and she will continually REFUSE, then become surprised when the guy cheats or dumps her. Like what did you expect the guy to eventually do? Among the top male requests that women bad at sex refuse: anal, lingerie, doggy style, outside sex... Of course the list can get extremely long and the refusal of anything beyond the missionary position. 3) All kinds of guilt, body image problems, insecurities, weird fears, paranoia, mental problems about sex Some women have severe anxiety about being naked, because they think guys want perfect bodies. So if their breasts are small, nipples big, butt a bit flat, etc... they don't want to get naked or act nutty. At times a guy has to become a psychologist to help reassure such women, but NOT every guy wants to waste time doing this. If a woman seems too crazy or insecure, many guys will walk. 4) Having no flexibility with her legs, in ability to open her legs. This is a major hidden problem and the cause of bad sex for a lot of women. They need to stretch or take some Yoga classes. Because they have no flexibility, sex can become uncomfortable, quickly tiring, or make their legs sore. Women who are flexible are usually very fun and exciting to be with, while stiff and inflexible women are the opposite. 5) Squeezing her legs together tightly and uncomfortably, and thinking that makes for a tight vagina. Some women don't know what vaginal muscle control is, and think squeezing their legs tightly together will make their vagina tight. Ah, NO it does NOT! Women like this often cause awkwardness and weirdness, as the guy tries to open her legs, and she is trying to squeeze and prevents the guy from moving or pumping. 6) Squeezing the vagina muscles too tightly. Inability to relax. Such women often have weird mental issues about the tightness of their vagina that they take it to the most EXTREME. They incorrectly think that JUST squeezing their vagina means good sex for all men. This can be to the extent that penile penetration is extremely difficult and the woman's vagina hurts after a short time due to FRICTION or damage from the penis trying to get entry. Often women squeezing their vagina muscles excessively, can't do sex for long and complain of pain. Such women haven't learned that vaginal muscle control works 2 ways. RELAX and tighten, OPEN and close. 7) Loose vagina The opposite of the above (too tight vagina) is the loose vagina. This is NOT usually a problem, unless the man has a very small penis and it's less of a problem for women that can do ANAL sex. In this situation, it's hard to say if the problem is the guy being small or the woman having no muscle control whatsoever. The key here being if the woman is unable to control her vaginal muscles at all. This is easy to check. Can the woman feel her vagina squeeze around 2 fingers, an average size dildo, or penis? 8) Very awkward and clumsy movement, no sense of rhythm This is one of the MOST DIFFICULT problems to correct. The woman having no sense of rhythm and moving very clumsily in bed. Many times, this is due to lack of sexual practice. It can also be because the woman gets excessively nervous, or never played sports or did dancing when they were younger, so didn't develop a sense of rhythm. Over time and with lots of practice, some women improve, but can the guy tolerate such clumsiness for a long period of time? 9) Fake sounds, over the top noises and screams, or dead silence Guys who have experience with many women, often can tell the difference between real and fake sounds. Nothing more annoying than the feeling the woman is bullshitting or an actress. The flip, can be dead silence, and a possible cause is the woman is afraid to express herself sexually. Natural and honest sounds of pleasure are the best. 10) Non-sex related activities, during sex The worse offenders I have ever seen or heard about are heavy smokers and prostitutes playing with their phones and texting or calling other customers. A pro playing with the phone is plain disrespect and demand a discount or call her agency and complain. If this is a non-P4P or girlfriend doing this, time to strongly consider dumping her. If a woman seems like she can't go without a cigarette for 15 minutes and smokes excessively, be warned that this very bad habit may carry over into the bed. 11) Bad blow jobs, biting the penis I think this is a true litmus test of how much a woman likes penis and how dedicated she is to being good at sex. Size of the mouth, size of her hands, and usually size of the penis isn't the main factor. Even if a woman can't deep throat (which takes dedicated practice), she can at least suck the head of the penis (no matter how small her mouth is). I've also met women of the same height and mouth size, where one woman says deep throating is impossible, while the other does it easily. 12) The false belief that all other woman are equally bad at sex Women that are bad at sex, can often think that "normal" sex means being bad at sex or that all other women are as equally horrible at sex as her. A curious verbal indicator that a woman may be horrible at sex, is when she insists or says something like, "I only do/have normal sex.". This actually often means that the woman doesn't understand that sexual variety and diversity IS NORMAL, so she is very limited and clueless. She may not realize what other women CAN and ARE DOING.
