I did once enquire of Bjanee about a gangbang - she said no A levels "for obvious reasons".. not obvious to me, except that maybe she wouldn't want a dozen blokes banging her up the arse.
So I would think DPs aint going to happen either, and with up to 7.5 blokes per girl, you're going to spend a lot of time on your own.
I would like to DP a girl sometime, but the thing that puts me off parties generally is the safety. You (and specifically your cock) will come into contact with another fella's fluids at some point.
