Bisexuality now has nowhere near the social stigma it used to have. It's pretty much just thought of as how we are nowadays.
My 30 year old niece said that everybody at university was bi, or curious. I go to a swing club, and bi is the norm. It's a very healthy way for society to be.
There's still on really weird double standard among the general public Bi-girls HOT! Bi-men GROSS!
I think men fucking men, and women fucking women are equally cool, if it feels good, do it.
I was talking to a man and conversation turned to anal sex.(with me it always does) I asked if he had done it. Yup, he loved it, and did it as often as possible. I asked if he's ever had anal with a guy. He looked at me like I was totally crazy, and said- That's disgusting, sticking your dick into some guys shit!
