Re: Increase sexual sensitivity
There are things you can do to increase the sensitivity of your penis, so that you can enjoy sex more. Usually the first option doctors present is pharmaceutical, but you may want to consider that there may be long-term side effects including accelerating the desensitization that comes with aging.
Without any potentially harmful effect, you could also try keeping your glans protected from rubbing against fabric in your clothes. This can increase sensitivity quite a bit (reversibly). There is a product called the "ManHood foreskin substitute". It's a little soft fabric pouch to wear over the end of your penis to shield it from rough fabric. Wearing it for a month is said to make a noticeable difference.
Another option you could try is controversial within the American medical community, but it is the most effective thing you can do to increase the sensitivity of your penis: nonsurgical foreskin restoration. (Technically one can't actually restore foreskin but it's possible to regrow something very similar. The foreskin is essentially just a continuation of the skin of the penis. Unless there's excessive dorsal and ventral nerve damage prior to the circumcision scar, you should be able to regrow new nerve endings in the new skin. You can't regrow the specialized fine touch receptors or all the original connective tissue structure exactly, but nothing else can give you new nerve endings on the most sensitive part of the penis.)
It's obviously a big commitment. It has to be done very gently and very slowly or the skin can tear and scar. It takes a LONG time (1-3 years); and it alters what your manhood looks like (when flaccid--with an erection foreskin retracts only making the penis wider behind the glans, so it only appears as increased girth). But there is no other way to grow new nerve endings on the penis. You can read more about it elsewhere on the internet.
There are contraindications like UTI or STD infection, latent infections like HSV & HPV, or the presence of a scarring disorder, so it's absolutely worth consulting a urologist before beginning. Unfortunately, the majority of American urologists don't know anything about foreskin restoration, so you'll have to find one who does to talk to about it. (And unfortunately just because a nurse or receptionist says that a urologist can advise you about foreskin restoration does not mean that is actually true, so it seems like you need to insist first to ask the doctor personally whether s/he will be capable of advising about it before you seek--and pay for--a consultation about it.)
One key advantage of foreskin restoration (and foreskin generally) is that because it increases sensitivity, it drastically reduces the pressure that you need to feel adequately sexually stimulated to enjoy sex. High friction sex and especially masturbation can definitely accelerate penis desensitization.
