Thanks for all the replies.
I don't offer OWO, but I find that if I manually stimulate it tends to result in precum. Solutions: 1) try not to be so good at handjobs
or 2) condom on earlier. Today when I was working I tried to move the condom moment forward a bit. Some guys really seem to dislike this though.
Natalie, just on the point of putting it on while 'soft' ... I'm fairly certain that the condom is not meant to go on until there's an erection, or it might not quite be on right. Still, if it works for you then carry on.
I think I am going to try and put the condom on a bit earlier, and if there are any doubts about whether it might be on my hands I'll use the 'oh god, my hands are just too slippery to open this condom packet, ahaha ... " excuse mentioned above!
