OK so basically I can have unprotected sex and get completely wet sometimes more then others but as soon as a condom is put on I no longer am wet. It still feels good and I still enjoy it but I have to use other means to make it so its wet... what could cause this and how can this be fixed?

It's a psychological thing. Somewhere in your head, a little voice is saying "Condom? Can't get pregnant, can't be bothered getting excited." And you don't get wet.

It's not a reflection on you or your partner, it's just that bit of you that wants to reproduce is getting into the act. Put manners on it, and dig up the lubricant if necessary.
