Hypersensitive Glans?

You don't have to get circised to solve this, unless you want to, but leaving it back (permanently retracted) will let you lose some of that extreme sensitivity (not nearly so much feeling loss as would be the case if you went for a circision and had the foreskin removed), but you'll be able to enjoy and take the time to enjoy that which you haven't been able to till now. You'll probably have to take it slowly, as it does take a little while to stretch out to the point that it doesn't tighten and cause a problem, or roll back again, but I think you'll definitely be much happier.
