He said that since we've started having sex he really hasn't masturbated at all. I doubt, if he did have problems with it, that he would say anything to me about it. He has been to the doctor for a suspect lump that turned out to be just a cyst and the doctor said he was healthy in that area.

He's not on any anti-depressants. He is a graduate student and will be defending his thesis in December so I don't know if the stress from writing his thesis combined with classes may be effecting his concentration or mood? He still seems really chipper like normal but he is a guy so maybe he's just not talking to me about being stressed.

The thing is it doesn't really effect performance or my ability to....y'know....get the job done. Both of us are still satisfied. Luckily, he's big enough that, even if he doesn't have an erection, it's still big enough so it's not like it makes things more difficult in that area. I'm mostly just worried that it could point to other problems. And I know that things like diabetes etc... can effect that even though it's not a sexual disorder.

I do get your point that if I bring it up with a concern for his health that he won't take it as me putting him down. I just know that that's a really embarassing thing to bring up. It'd be the same if he came to me because he suspected I had a problem. Even though it would be for my health, I would still be really embarassed that he brought it up in the first place. Oh well.

Thanks for the advice.
