Now that you're being sensible: what would you suggest to fix that? Lubricant like a mad man?
I'm ever-sensible, good sir. All the same you'll just need to be more alert to the situation at hand; sometimes it's not a problem and sometimes it is, sometimes you'll need lubricant and sometimes you wont; a healthy female should easily maintain sexual relations without lubricant but some are not so healthy and others are not predisposed to producing enough lube to handle a circumcised penis.
A few tricks of the trade are to keep the penis inside the female, this is because what actually dries out the vagina is the constant motion in and out and the fluid on the penis itself dries in the air, the glide motion of the foreskin prevents the amount of movement that causes this effect, so it's not actually your penis being unnatural for the record, it's just that the extra skin helped hold moisture in the vagina. So less in and out and more pushing deep, shorter thrusts, etc. will help with females who are not lubricated to your satisfaction.
Another good trick is to be patient; the more a female is turned on the less of a problem you'll have, finding a good rhythm, etc. ( all essential for good sex anyway ) are now more important for you, but you'll get the hang of it soon enough and understand that.
As for the sensitivity and desentization, there's no trick and there's no cure; you can cover your penis and it slows the effect but it cannot be stopped and truthfully you may or may not notice a difference in sexual gratification
although let it be known that many men have reported more, not less, sexual pleasure because while your foreskin does have nerves, and a lot at that, it just isn't the same as the head of your penis with nerves that had never been touched before and the sensitivity amongst those nerves are different than that in the foreskin, attributing to the greater amount of feeling.
But.... I'm just a kid. You'll find out as you travel down your own road, no?
