Many men, especially young men, find that the foreskin is much tighter over the head of their penis, and so, rolling it back to expose the head or glans, is much more difficult when they are erect.
Take it easy. Remember, his glans or head of the penis is just about as sensitive as your clit is. You wouldn't want someone just jumping in on it and trying to pull it out from under it's hood... so take it easily when rolling back a foreskin. Ask him how he likes it. He'll probably be able to show you.
Otherwise, yeah, it's pretty much the same, except there may be some things that he'll like more...and some things he'll tolerate less. Go slow, explore and ask for feedback. "Do you like this?" "How about this?" "What else would you like?"
You CAN do it the same as with a circumcised penis, but the acorn and the inner foreskin are mucous membranes, like the mouth, and are more sensitive than if they were allowed to dry out, as after circ. You can spread the opening of the foreskin a little and gently inflate it like a small balloon, or you can insert your tongue. Even without retracting the foreskin, very light rubbing on the outside can bring exquisite sensations to the man. If you are concerned about cleanliness, the natural penis is no dirtier than the vagina. If you ask him to let you let him wash it, he might find that a turn-on. Don't be surprised hif he avoids soap--it can cause irritation and is not necessary. When you feel the csuhioning effect of the foreskin between his coronal ridge and the lips of your vagina, you'll realize what you have been missing.
I've started oral on my boyfriend while he's soft and have inserted my tongue under his foreskin before.
And did he love it? My b/f. Has an issue with getting hard, due to medications diagram diets work well, any suggestions?
