Hi, awhile ago I fooled around with a guy. Let make it clear that we did NOT have sex. No vaginal, anal or oral sex. We touched eachothers genitals for a very brief period (2 to 3 minutes) he rubbed his penis on my underwear for a second before he fingered me and i touched his penis then got on top of him. He had a sheet wrapped around his body so our genitals wouldn't touch. I had my underwear on while on top of him. I did not dry hump him only laid on top for a few minutes. I had my underwear and shirt on. My main worry is the fingering. Could being fingered spread anything? I'm an anxious person in general so I'm worried. To sum it up: no sex at all, genital touching, he had a sheet covering his penis so our privates wouldn't touch and I had my underwear on. Is HIV or other STDS possible from this?
