Yes, it probably means your gay. Now that I've said it, what does that do for you? Do you want to be gay? Does that smash your entire conception of your sexuality? On the flipside, if that DOES make you gay, do you suddenly not enjoy it or never want to do it again? Or does it fill you with guilt and questions regarding yourself, and why a previously conceived "heterosexual" would enjoy something as blatantly gay as having a load of semen shot onto his face?
Stop worrying about labels my friend and simply enjoy life, sex, and all there is in between for what it is.
