Two interesting messages regarding yesterday's post.
"My BF didn't like to admit he jacked off and always had the same problem of coming too soon. I came in very late from a nite out with my best friends tiptoeing in so I wouldn't wake him only to find him so into his dick that he didn't notice me. After he came I told him in a very soft voice God that was hot. Problem solved bc now he does it for me or I do it for him. Sometimes I'll give him a bj. Then he recups a little bit and we go for it. Tell your hubby you think its hot to see him stroke his dick."
"I wish my husband had that problem. There are lots of times I just want him to get it over with allready. Once I actually pushed him off me and told him to finish it himself went and showered and when I came back out of the bathroom he still hadn't cum."
Ah, the two extremes of ejaculatory control. It happens to more men than most would like to admit.
The first issue can be resolved by cumming shortly before engaging in other sex. Or --- though I failed to mention it yesterday --- if extreme sensitivity is the base issue, there are Over-The-Counter (OTC) desensitizing creams available at almost any pharmacy. This issue can happen with uncircumcised men.
The second extreme might be solved by learning to stimulate the prostate. Your boyfriend can learn to do this during masturbation by squeezing his butt. Or by exterior stimulation with his hands. Then, once he's learned to employ that movement, he can certainly do it during penetrative sex.

Or you can provide the added stimulus with your fingers if you're in a position able to reach the area.
If it's a lack of sensitivity, he may have an issue with callous (a thickening of the dermis) on the head of his cock. This can happen to circumcised men due to the constant rubbing against clothing.
This can slowly be shed by using a few drops of Vitamin E oil after a shower. Leave the glans slightly damp and spread a few small drops of the oil on the entire cockhead. It is not an overnight solution --- but, then again, nothing worthwhile happens overnight. But after a few weeks, he should begin to notice a difference in sensation.
