If your soon-to-be DH or your DP is going on one of these weekends, perhaps you should watch Stacey Dooley Investigates: Sex Drugs and Prague on iPlayer and see what you think (it was shown on BBC3 on Monday night)
I've read a number of threads where most women seem happy to pack their DPs off to Prague, thinking that the worst that could happen is they'll hopefully won't spend too much money, get mugged or fall over, and the less sensible ones might end up quietly leering at a couple of strippers behind their beers in a raunchy bar.
However, according to this programme, going to a lapdancing club to see strippers and have private dances is pretty much standard on a stag weekend. Prostitution is officially illegal, but the brothels just call themselves lapdancing clubs instead. The prostitutes and health workers Stacey talked to said that 'every other man' tries not to use a condom, 5 out of 10 men in a stag party use the brothel's services, and the stag is 'always' one of those five. Many men even want to have unprotected sex with prostitutes who have HIV, which they see as some kind of thrill, a bit like bungy jumping.
Added to the fact that condoms can't protect you from everything, and any prostitute who has to sleep with a lot of men probably skin infections (herpes, genital warts etc) and that's quite a public health problem in the making. These guys will be coming back to sleep with their new wives and passing HIV on to them, which they may not find out for some considerable time, ie when the AIDS symptoms kick in. If the men come back with herpes, the couples will be finding out about it rather sooner, but as herpes is incurable there'll be nothing they can do about it. You can throw out your cheating partner, but you'll then have the problem of finding a new one who's OK with you having HIV/herpes.
If these issues may affect you, perhaps the best thing is to watch the programme on iPlayer and see what you think. The DM has also done its own shock/horror story on the programme (which is available on iPlayer until Monday 14 Oct), which I've included a link to as it does offer the convenience of a summary of the programme if you don't have time to sit through it.
