I just used one today ... I got some free adjustable ones in the gift bag from the GigaGolf outing in Phoenix .... I'm sorry but i can't recall the company that gave them away ... but i told my wife lets see if this works and I'll tell ya what ... there wasn't a big difference in the time i lasted ..it was average about 15 mins of intercourse ... but it was a bit harder and every vain pops out ... It was a bit more sensitive and my wife said the veins and rim of the head made it feel a bit like a ribbed condom .... more friction .. over all i think it was cool ..i wouldn't use one all the time but it was ok....
