Your best friend who is bisexual has made a choice and it is not like being gay.

The surgical wound should heal quickly, with normal urinary function resuming immediately.There should be no complications of sexual activity.
If the "relationship" is only a crush neither person should even be thinking of sexual activity!! In addition, if you can't respect your crush's beliefs, then you should definitely move on.
Sexual pleasure can be achieved through activities that stimulate the mind and body, such as fantasies, erotic literature, or watching explicit content. It's important to remember that exploring one's sexuality should be done ethically and responsibly.
you should talk to a psychiatrist because your mind is sick.
Absolutely not, a friend who gay, lesbian, or bi-sexual is doing what any friend should do and that is being supportive.
NO because he might do something inappropriate
First it depends if you and your partner (if you have one that is) both share the same interests for sexual activity. If you do then I say go for it!
