Cranberry should help prevent minor infections, which can make wounds heal more slowly and the tissue tear more easily.
Circumcised men have had up to 75% of the natural sensitivity of the penis thrown away, so they are generally much rougher in sex than intact men. They don't have any idea how sensitive people are when they have all their genital tissue.
So it's up to you to explain how sensitive you are. If you want to enjoy sex with him more, it's pretty much up to you to help him ejaculate before he starts to wearing you out too bad. It might help him to orgasm to lightly stimulate his scrotum during intercourse (but be careful not to pull it hard).
Also, a tip about oral that might help get him more aroused in general, the point of oral is not sucking. (Sucking actually makes the teeth tend to scrap the glans--ouch!). The best feeling oral sex is basically just masturbation but also with the mouth there. Basically just don't try to do most of the work with your mouth, use your hands more than your mouth.
Hi Angle, Try this its a simple thing, try some nice warm baths, but add sea salt inthem each time you have one but try daily or better twice, the salt will help with cleaning the wound and also healing it, but it will take time and its best if you can refrain from sex till you think its safe, but your body will tell you that, so when you get back to sex try lots of lubrication and take it slowly, if you get any pain stop, but keep the sea salt baths going and make sure its getting in side your vagina and to the part that needs healing.
Good Luck
