Like let's say "rhetorically" she gave me a handjob and she had an STD, could I catch it? How about if I fingered her and then masturbated without washing the hand? I don't know if she had an STD or not but I'm getting some dry skin down there and its worrying...
STDs typically occur through the exchange of fluids. Even if she had the worlds sweatiest palms, you won't get a disease from her touching you, unless of course she was covered in her own juices. Did she get her juice on you? Dry skin happens. Be worried when you get discharge or new bumps/growths/rashes or when it is painful to pee
Just a small amount of her juices. I think I'm ok though, it might be the lotion she was using on me that caused the dry skin. So... how do I get rid of dry skin, it's annoying lol.
if you went from immediately fingering her to masturbating yourself then there would be fluid transfer and possibility of std's
