It's a bummer Bozo! Isn't it? Stay cool! Were you able to improvise and at least get a BJ or HJ to salvage the moment?
Seriously, if I recall from your previous post, this was suppose to be your first time. One can very easily tend to forget certain things the first time. Did you remember to pull the foreskin back all the way or as far back as it will go prior to putting on the condom? Also, prior to putting on the condom, try unrolling it a bit, and kinda snap it on (softly) over past the gland and unroll it the rest of the way. Piece of cake. Yes, you might also want to try the Magnum condoms. That's what all us men always use.
