I used to think this was all black and white.......finally realized there are many layers, shades, and comfort levels with sexuality....
some straight guys can only bottom if they're messing around with a dude, some guys have to be giving head to get off, some bi? guys can only have an emotional relationship with a woman but are very happy to physically mess around with a dude, some straight guys love it when their wife or girlfriend uses a strap-on with them, some gay guys don't want anything near their butt, some other guys..........well, you get it......
