This is a great thread.
I think us blokes get paranoid as being quick cummers is an insult thrown at men by women, like 'having a small cock'. Reading on here the comments from experienced women, it probably makes little difference as it's the overall experience that counts. I love the foreplay side and if I've made a woman cum before full sex I tend to be more relaxed and last longer but if not I can get a little anxious and this tends to make me cum quicker but long enough to cum at the same time which is just the best thing in the world........
