Penis less sensitive

Hi there. Thanks for posting your question on Ehealthforum. You might like to send it in again only this time using the Ask A Doctor format.You do not give enough details like age, sexual history and so on. From the little you do tell us I would not be too worried but, as I say, one would need more information.

Well... I'm 20 years old and I always had the mood for sex! Have never been diagnosed with an std though an ex was diagnosed with (fungi?) and I did the treatment that her gynecologist suggested we both do. I am worried that I didn't do as I was supposed to do the treatment and I still have the same thing or mayde it could be smething else. It could also be (could it?) psychological 'cause my last girl, when I touched she went "Oh, that hurts!" That includes kissing,touching her breasts, penetration (well... trying to), using my hand to give her pleasure etc. Oh, my tongue didn't hurt but it tickled so that's out too! What do you think, could it be psychological?
Is there any test that would diagnose all or most of the stds?

P.S. Yesterday it didn't but today, my penis itches a little (and not always, might be irrelevant). (I used the expectein cream before going to sleep and the itch is out and not on the glans.)

Please change the title of the post to "Penis less sensitive and low libido." (I don't know how to do it.)
