I 'm 19 and have had only 2 sex partners. My first boyfriend had a thin cock (7.5 x 4.5), but he would pump me for an hour or more, being in full control of ejaculation. So this being my first partner, I got the idea that this was a normal length of time for intercourse. It certainly satisfied me!! My new boyfriend has a shorter but thicker cock (6.5 x 5.5), which is OK for me, but the trouble is, he can only last for about 3 or 4 minutes at best - and its not enough for me. I like him a lot, but the sex is frustrating compared to what I was used to before - an hour or so of glorious pumping. So girls, how long does your man perform??
