First of all a lot of males are bi-curious and even experiment. For most it's just a 1 time thing or a few times and that's it. For others it stays with them.

Your going to hear people swear they are 100% straight or 100% gay. I personally do not believe that is possible. There will always be a ratio and it could be all over the map.

For example, a person could be 50/50, or 75/25 preferring women. Or 75/25 preferring men. I don't think sexuality is a yes or no. I'm sure there are a lot of men who are 98% str8. And a lot of gays who are 98% gay. I just don't believe there is such a thing as 100%.

Just my 2 cents.
