Ignore dunderhead over there. If you like the person go for them, if you want to just have sex, you can go to a bisexual club near you and if you want sex with a person there let them know its a one time deal. If you want to be in a relationship with a certain person you cqn ask them some things like, are you for or against gay or lesbian people. What would you do if a lesbian asked you out. Basically get there opinions on bi lesb and gay people. Try to change their thinking on those type of people if they are against them. Make sure you know if they are straight or what because if they are then it will be akward between you both. You could always go straight out and say I'm bisexual and I would like to date you. I hope this helped because I wish you a great deal of happiness in life. May fates hands guide you amongst the angels that wait. Seriously though I hope it helps.
