Gay men.
I once worked at a very shitty hotel. We're talking a hookers 'n heroin type hotel. I once had a family in July come to the front desk at 3am complaining that this hotel was NOT suitable for a family to stay at. I simple said "Oh, I fully agree. This place ISN'T made for family vacations. Why ARE you here???". She didn't have an answer for that. She was atrempting to use that as reason why she should get a refund. She had no idea how to react to me saying that she WAS in the wrong place, she WAS in danger, and the smart thing to do was leave now for her own families safety.
Well, about a year after that we had a gay leather biker convention that booked 80% of the whole hotel.
While I was checking this one guy in, another guy walked up behind him and asked "Hi, I'm Tom. Are you single to play?" The first guy says "I'm not single, but we're free to play". The second guy just said "Great. I'm in room 302. Here's a keycard. Bring your boyfriend and all your friends."
Me, being a straight male just had to be amazed at the efficiency. Tom just went from being a stranger to hosting a threesome, potentially an orgy, in 3 sentences.
Not even the germans are THAT efficient! I just stood there thinking "God dammit. Why can't I be gay? That was SO easy! With women you have to do all this other pesky stuff, like learning their name, going to dinner, finding out who they are as a person.....Tom basically just walked up and said "Come get laid".
I think gay guys give more blowjobs just based on the fact that with a straight couple, only one is giving blowjobs and only sometimes. Gay guys BOTH give blowjobs, and I assume it's several times a day. Like one just walks into the room, shoves his cock into the others mouth, and says "Oh by the way, my parents are coming to visit this weekend......don't stop. I can multitask."
