Kind of in response to the guy who went to the strip club, but I guess you're just an average bloke. At least that's what I tell myself after I did something similar.
A while back I went on a stag do to Amsterdam, leaving my girlfriend of several years at home. I somehow found myself away from the group and was fairly drunk late at night. Now the idea had never really been in my head but for some reason, in my drunken state, I thought, when in Rome..
I wandered round a few of the streets checking out the talent and trying to build up the courage to actually go through with it. As I was looking a stunning blonde beckoned me over and next thing I knew she had the door open and I was following her in. As I went in, she asked if I wanted her friend to join in as well. This seemed like too good an opportunity to pass up so naturally I said yes.
Long story short and without the gruesome details, I ended up having a threesome with two porn star hot prostitutes while on holiday without my girlfriend and it was fantastic (and reasonably priced too after I haggled her down with my beer logic). I don't feel any guilt for what I did, no one knows about it and I've often thought about doing it again over here.
