Though it is possible to ejaculate with prostate stimulation, it's generally better in my experience if you try to orgasm through stimulation of the penis with some prostate stimulation. It makes the orgasm more intense. Some others, though, prefer straight prostate stimulation only.... it's all up to what you like. Best bet is to try it yourself to see what you like.

i want to try anal stimulation with my boyfriend, i just don't know where to find a guy's prostate in there.

any idea on how to do it right?

I've replied to this question in the thread you started.

physiotherapist I fingered my anus, which believe it or not is quite a turn on. Heres some tips. First be gentle, don't force the finger in. Secondly try one finger to start with. And also remember the most important rule: have fun! lol

cool!!!

thanks!
