Hey Emile, on their brand website they have a page which you can click on to customize a fleshlight.

Hey Bungeedog, it sounds like he's suffering from situational anorgasmia. Basically it's an orgasmic dysfunction where he can cum in one situation (like masturbation) but not in another (like having sex with women.) There are a few options. It may be a serious enough condition that he needs counseling if his problem is caused by a psychological condition. Is he under a lot of stress? Are you trying to conceive? Is there any underlaying cause that you can think of off the top of your head that may keep him from reaching orgasm with you? The best start is to talk to him about it, however, he may feel inadequate so if he starts to withdraw from the conversation, don't push it.

There may be a simpler reason too! 

When men masturbate, we tend to use a ROUGH hand, stimulation that's harder and faster than when we have sex. It happens to a lot of younger guys because we've trained ourselves for quick and fast masturbation. One thing to try is not to have him stop masturbating, but to have him masturbate with a softer touch, and try masturbating with a condom on. It may take a while to retrain his body to respond well to gentler stimulation. Does he masturbate with just his hand? Or does he use sleeves or pocket pussies? If he uses just his hand, than buy him a soft toy with a silky interior that will encourage softer masturbation like the Fujiko velvet touch, which is a favorite of mine.

A vibrating cock ring would be a great aid, for you both! My favorite is the Cock Ring and Egg by Pipedream. Also, you could have him try a prostate massager. At first a lot of men are objective to anal play, but it may be the added something to give him the edge he needs. Dr. Joel Kaplan's
