My boyfriend is circumcised and I seem to find it more difficult to pleasure him as much as I could with guys who were uncircumcised. I mean I guess most of the pleasure in "un-cut" guys from the gliding motion of the foreskin down the head of the penis, but if a guy is "cut" and the head is permanently exposed and rubbing against material etc. it will surely become more desensitised? So where do circumcised guys still feel a lot of pleasure then - the base of the penis or so?
Well, I was with my boyfriend before he had his operation and then afterwards, when he was circumcised. I haven't had a single problem is pleasuring him orally but maybe your technique has to change a little. Reduced sensitivity is expected but my boyfriend says, as soon as he becomes aroused, it is almost just as sensitive again. Your boyfriends experiences may have been a little different though and he may be less sensitive now. Ask him for feedback on what he likes and doesn't like? His balls may be more stimulating for him although don't forget that the tip still is really sensitive. PM me if you want to talk about it but not infront of the rest of the thread readers?
i second the thought of being sure to have lubrication. if you use your hand you'd better be sure you used lube.
else: most likely it's not harder to please him than any other guy, but for some people it's true, that they are less sensitive.
but then everyone is different anyway? why don't you try? where's the problem?
