My boyfriend gave me oral. I'm worried that he could've had sperm on his hands then put them in his mouth then made contact with my vulva. After that we had dry sex. We were both wearing underwear and Jeans. We were doing it for a while. I felt really wet afterwards and I noticed a wet patch on my jeans where my vaginal opening is. My boyfriend said it was from me but I'm not sure. I didn't see anyway patches on his jeans but maybe they just weren't visable? There was a wet patch on his boxers tho. Please help me :(
