OP is it very heavy with the man on man action at this place? that would be off putting. or is it more spit roasting, woman sucking two cocks at once sorta scene?
The vast majority of the sex that goes on during the parties is hetro and nearly all the man to man stuff is either a hand job or BJ. There is very little anal sex or same sex kissing. I have seen both but when I do I tend to move to another room as its not my thing and I don't even want to watch it. Everything at the party is consensual and No means No so nobody is going to rape you or do anything if you don’t want to do it. It is a very big house with different play areas and if you want to you can walk around with your clothes on watching the action before joining in.
I consider myself a “man slut” rather than being bisexual. I’ve never kissed a man on the lips in my life and the thought of doing so is the same I’d have if I accidently touched vomit or shit, its yukkky. That being said I don’t care who touches my cock as it still feels good to me and I can’t tell the difference between a male or female hand and in a group scene who cares anyway. I’m sure a lot of the other men at the parties are like me. £55 is cheap for a party where there are paid party girls willing to fuck anyone but for a gay man they can go to a gay sauna much cheaper so the guys who attend even if they’ve got bi tendencies aren’t hardcore gay.
If you go and don’t want a guy touching you my suggestion is that you indicate you’re close to cuming and you can do that without having to explain further. You shouldn’t say it’s because you’re straight. The problem with admitting you’re straight isn’t the management who you rarely see in the playrooms but some of the regular greedy girls. There are several ladies who are swingers and are at most parties and if they hear anyone saying they are straight they will give them a right tongue lashing. These ladies are good fun but they are hard bitches so I wouldn’t get on their wrong side.
One thing that hasn’t been mentioned is that there is a fully stocked dungeon. As well as not being fully bi I’m not into bdsm but I’ve witnessed some very kinky and extreme stuff in there. If you are bi and/or into bdsm you’ll love what's on offer at the parties but even if you’re just a horny bloke looking for a cheap couple of hours of fun its worth checking it out.
I hope that helps and I don’t sound too much like a tout.
