I had sex with a tranny 10 weeks ago and now i feel paranoid when i inserted for anal we used a condem and when she atempted to insert in me (she couldnt get hard and it kinda sat on the rim) i sure we used a condom but im afraid i may be mis remembering my real question is if in the event that we didnt use a condom which i think we did but im scared would 2 mins of a dry hump of her penis rubbing to outer rim without penitration put my at a good risk of hiv?
