I wonder what the avg refractory period is? I was seeing some porn and I noticed that most porn stars seem to stay hard for a couple minutes after orgasm. I usually go down and out once I come, but I can get hard again in about 20-25 mins. I've noticed that depending how I feel about the girl or how turned on I am can sometimes change my routine and have back-to-back orgasms... I think the most I've gone without going limp is 4 in a row, but I'll probably never do that again since it becomes to sensitive after like the third orgasm. Is there anyway to extend the refractory period? What is normal?
