We had sex on the first of February then on the 15 we had oral sex and he wasn't cuming when I was giving hkm a blowhob so he jacked off and then I finised and whils he was touching himself I think he could have had semin on his hand then he fingered me. Ever since we had sex my body has been acting weird and then after the oral I have been having weird cravings and I'm nauseous but haven't puked. What could be wrong? Oh and I know I'm not pregnant I had my period.

Sounds like this is all in your head, or you're coming down with something.

It could be anything, including an STD. Is that why you mention having sex with your boyfriend?
