I mean, no bi option? It's obviously the best choice.
I wish I was bi.
But if I couldn't be bi, i'd rather be a lesbian honestly. I personally dont' get why any girls wanna be with guys personally, and that is outside of what my natural attraction is. Guys get girls pregnant (there is always the risk), unless the girl uses protection (Which usually has side effects) or they use a condom etc.
There are certainly some things I wouldn't like about being a girl (not really wanna to try the whole period thing for one), but i'd certainly have had more sex when I was younger if I was one lol.
If you asked me. asexuality is better than all. But the choice is between gay and straight in this thread.
