Oh yeah, a couple of items you might want to make use of (or not depending on if your mind is evil enough to use them).

*Taste* is an interesting issue. I'll just note that aspagus is reputed to make semen taste *awful*. And pineapple juice rather improves the flavor. Other than that, it's a matter of (forgive me) taste as to how palatable the stuff is.

On second thought, I'll refrain from the info on the "internals" of anal sex unless you plan to go into any details about it. I'll just note that the prostate is definitely a male "g-spot". :-)
