Okay,
Me and my partner have had sex like, 3 times. Each time we've had sex, the condom has begun to slide off, every 5 mins or so I'll withdraw fully, slide it back on nice and snug, and continue. It doesn't slide completely off, so my 'head' and about 1/2 of my shaft is still snug inside.
I'm going to buy smaller condoms, I guess the Durex Sensitive and Durex Elite ones are slightly too big for me.
I haven't been putting her and myself at extra risk have I?
