1.a mate who is perfect for you in every way and is everything you've ever wanted, EXCEPT that although they are attractive and perfectly good at sex, you have .0001 desire to have sex with them.
2. a mate who is disrespectful and even hurtful at times, difficult to trust, and has serious mental and physical issues, but for whom you feel passionately about and love (!!) having sex with.
3. I'd hold out for someone that is, ideally, a combination of the first 2 mates - knowing that I am almost definitely losing my chances at being with either every again and not knowing if/when I will find that ideal mate.
