The more you want something usually the more desperate you seem and the more that repels women. As a woman, I would suggest following the advice of others and focus on working on yourself (mind, body and soul.) Not only with the intent to attract women but to be happy in yourself so you don't feel the NEED for love.
As for causal relationship....there are SO many opportunities for that. Just keep yourself open and expose yourself (not literally
) to new experiences and types of people. Let people come to you, if you chase to hard and too soon you'll scare them off.
Owlet, I don't think your example is that helpful in this case, as you are clearly using, (and I hope im wrong here) emotionally manipulating, or at the very least, leading on two women when its quite easy to get laid with out emotionally hurting others and being honest. Sounds like OP looking for actual connection and a relationship. I agree, however that you shouldn't rely on anyone to fix or even complete you. It's just a shame you kinda contradict yourself there a little because, if you'd be happy without them, you'd let them go and they could love someone who would love them back
