@MrSStiffy,
varies person to person, time to time, age to age...
while i was still training for my profession an older guy said he could no longer get up and go again right after he was done, but it did not bother him, since he was finding he could go longer than he'd been able to as a young man...
happily, I think he's right, though that's dependent on how long it's been since I last got off, and how... energetic or adventurous my better half is.
i think my wife was surprised to find out i don't roll over and drop right to *****, so while i know that stereotypes are such for a reason, there's no universal...
well, except that Miss Mandy is universally beautiful, desirable, and wonderful... a combination i've only seen once otherwise, and that other angel is also graceful and patient, considering she has to put up with me 24x7!
Pax,
RA
