I am in my late 50's and have never experienced anal sex with a woman as my previous very long term partner would not consider it. My new partner, also in her 50's is an anal virgin but keen to try- she says that she will do it to please me and does not expect to enjoy it, in fact she is very apprehensive about the pain. Basically, my question is, given the naughtiness and the tightness a man can't last long down there can he? If i could assure her that it would be quick I'm sure she would be more at ease. And yes, we have read up on all the info about relaxation, lube, taking it slowly etc.
