I have a few concerns/questions. 1.) If I do love a girl, is it necessary to have sexual intercourse? 2.) Is it okay to have sexual intercourse with another female (I'm female) and not fall in love? 3.) I heard that if two females are close their cycles can sync up. Can that (not saying it will) happen to the two of us?
1. No. Sex is not necessary because you don't owe anyone your body. 2. Of course. People have sex without love all the time. 3. Yes, it can. It's actually common in dorms and in houses populated by multiple menstruating individuals.
1. Of course not. It's never "necessary" to have sex, no matter what the gender of your SO is. 2. Yes. 3. Sure. It can and does happen, although that doesn't mean it will.
