Arg, this has really put me in an awkward position. If I say I want to use protection, she will want to know why. Any more advice?

The only way I smell it is if I finger her before sex, then I can smell my hands. After sex my penis smells like her and its not too great, even after a shower.

Is this a STD? Should I get checked. I am definatly going to have to talk to her about it.
