Try cumming in a condom 2-3 times, save it (refridge) then warm it up when you are in a place where you can jo and enjoy it. Use a condom every time and eat the supply you saved from before. You will enjoy it more this way, unless of course you are actually able to suck your cock when you cum. Nothing like sucking sperm from a climaxing cock.
Interesting that almost all the reply, including myself is 50%or more straight. What does cum taste like for those who have done this. I get a sense that it feels like egg yolk since to me it looks like it. Never thought of doing this but this thread is facinating for its respondents who have.
Usually..legs flipped over your head, almost folding your lower body over your upper body. This will allow you better control. I like to hold off, just for a few, and allow the cum to ooze out slowly, right into my open mouth.
