I was at that very same "Bubbles" blow bang!! My thoughts on that was it was OVERKILL- way too many guys! I was there for about 4 hours and I think I got my dick sucked for a grand total of about 10 minutes!!
  As far as gang bangs go, I've been involved in several of them, and the key for me is to just focus on the woman, and at least for me you forget that there is anyone else in the room! And don't be homophobic because if you're going to constantly worry that you accidentally might "cross swords" then that's all you'll be thinking about and then certainly won't get a hard-on!
