Its funny isn't it.... but you know what, I think most people are the same, but think of context differently, or are not yet enlightened. rubish word I know but there you go.
for me, cos im a guy I can nock one out in a few mins, but quite like to make it a lot longer than that and I find that making it take longer ends with a bigger one. Like so many things in life, being patient has its rewards..
For women I find that once they realise they can cum with a gushing flow of juices (yes I know I am a little obessed lol) and sometimes girls go their whole lives not realising they can. once they realise they can, they can do it in much shorter times.. Sometimes even a minute or two. like allot of pple have said, given the right set of culmanated factors, it can be very fast indeed. Building of sexual tension seems to be the overiding thing that works..
to make it a bit scientific though, given a total non state of arousal, and just going to work on a girl from that point with fingers tongue and a toy, I reckon it takes about 40 minutes on average to get her to cum fully... so by that I mean a mind blowing screeaming pussy clenching, body shuddering gushing bed wetting orgasm.
