CouragousRabbit saidI don't know the population of Bi people in this forum but I have a question. I just do not understand why would you have trouble with picking being with a woman or man if you have a choice? Biologically speaking, a relationship with a woman is more "natural," unless you want to be different. From what I have learned, sexually speaking, sex between a woman and a man is more "safe" and less "dangerous" than the "other side." I am just confuse because there so many benefits for you to possibly be straight and stick to it since you are with a woman (which you should be if you are not a cheating type).
After reading your question here, in full, it seems like what you are really asking is why would a man pick to fuck a man instead of a woman? Which is really not a question about us bisexual men, it's more a question about gay men who wish they understood why they only like dick. Well, to respond to the potential question, which is actually interesting, about bi men, the reason bi guys have sex with both females and males is because they are the most sensitive of all guys, deep down in their hearts. What I mean is that bi guys judge people by their personalities, their energies, their spirits, their hearts. So, a bi guy may meet a woman who is sexual attractive to him because she is a good person and honest and turns him on. But he may also meet another male who is also sexually attractive, a good person, or honest who turns him on. Bi guys are the best to be with (contrary to the Puritian American and Western false choice reality that says you "must" be one way or the other, good or evil, happy or sad, or up or down). Bi guys are the most natural guys because they actually reflect the truth of nature: nature is rarely one way or the other, but there are muliple shades of gray in true life. Only religion (and usually those using religion to regulate and control human beings' natural instincts and behaviors) tells you differently.
