Been to a porn theatre a few times, and masturbation is about the minimum you can expect to see and do.
You're looking for the holy grail... a website where men and women group cam and get off. It doesn't exist. That is, it doesn't exist without paying money. There are dozens of free jerk sites, some good, some suck. In the past 10 years at least of looking around for that holy grail - I never found it. Men outnumber women at least 100 - 1, if that good. Women just don't get into masturbating on cam. They do however get into moving cash from your wallet to theirs. If you are unwilling to pay, like me, then either give up or get into other guys watching. Cheers
I know this is an old post but just FYI I have been a member on Bateworld for 10 years and it IS a sausage fest but there are more than just gay men on there. As a matter of fact most of the men are bisexual and a good number are straight. You do not have to be gay to enjoy masturbation.
Love porn theatres. Lots of spontaneous jacking and mutual jacking and more there. One time I was there and another guy about my age came in, just the two of us watching, seemed really nervous. He saw my wedding ring and said he was relieved another married guy was there as it was his first visit to such a place. We made comments about the porn for a bit until I said "well I don't know about you, but I'm going to jack off." I took out my boner and started slow stroking as he watched and eventually did the same. I told him I was impressed by his 8.5 inch dick and that is looked bad ass. He blushed and said thanks. After a few minutes I asked him could I touch his penis and he said sure. Soon I was stroking him steadily as he gasped and moaned. He soon said "that's awesome man. Only way it could feel better is if I was getting head " With that I got on my knees between his legs and started licking his piss slit, to which he gasped "oh fuck yes" as I sucked the mushroom head and licked down his shaft to suck his balls and lick his taint. Soon I was bobbing on him, jacking him off with lips and cheeks and tongue while playing with his sack. Before long he said "dude, I am so close! If you don't stop I'm going to cum in your mouth!" My reply was to suck faster and harder and moan "mmmm hmmm" on his dick. That drove him over the edge and he blasted such a massive nut it leaked out the corners of my mouth. I kept his dick in my mouth until he stopped oozing jizz then licked him clean. After he caught his breath, he jacked me off and I nutted hard. We exchanged numbers and still meet up today.
