I have been with my fiance for nearly 4 and a half years. He had a problem with his foreskin tearing (a few of years before I met him) and at the doctor's advice had a late circumcision.
He said that shortly afterwards he was incredibly sensitive (too much so!) but eventually the sensation deadened and ever since then he has been experiencing problems, if we use even the tiniest too much lube he literally can't feel anything and he has never since been able to cum twice in one day, because 2nd time around the sensation is not hightened enough. He also has the problem now that if we don't have sex for a few days for whatever reason, he goes back to only lasting about a minute.
Is there anything we can do to help this situation?
