My one experience at the LAX CumUnion party last September was "poor" at best--I'm not one for stand and model but that night there sure were TONS of guys doing just that. I got on the fuck bench, bent over onto the "stage", and propped myself up on the fuck bed and only one cock (no cum) the whole 4 hours I was there. Perhaps the guys weren't into my slim, smooth, twink build?? I had recently cut all my long hair off so am now very young-boyish looking. I know, not everyone's idea of hot especially here in LA. Funny, I did end up meeting a guy right before I left who was straight-identifying and I ended up taking him back to my place and got a load from him that night (and for a few weeks after as well until his woman came back into town).
My one experience at the TeamPig party back on July 4th was better--I did meet one Top who hogged my pretty ass all night so at least I was getting ample attention that night--on top of the dresser in the bedroom upstairs nonetheless (got to show off my flexibility with my legs up on the dudes shoulders or wrapped around his waist, and generally pointing up to the cieling whilst holding both him and me through all that thrusting lol) but again, I played with no one else and put myself on ready display for anyone's taking.
Even more interesting was the fact that of the Tops who have had the multiple pleasure of a 1-on-1 play session(s) with me at my place that I ran into at both of these parties made NO moves at all to fuck (or interact with) me in public/at the parties..? Still wonder what may be the case with this observation (I have my own beliefs)...
Point is, with group parties, the dynamic really does depend on the energy level of the sex happening there. I agree with NWUSHorny that the sex energy at the LAX party is quite high but despite this there still are more guys who stand and wait around than who are actually fucking (yes--I'm going off my one expereince there I know) but this is somewhat a normal pattern in LA that I have experienced and observed in many other places here which doesn't exist at the same level in other cities I have visited.
