It's kind of like going to a strip club: I was never the guy who got on the stage or threw money at the girls so that the whole club could watch her pick it up (to me, that's kind of what My Free Cams is like).
What I really enjoyed was looking around, watching the girls dance and then picking one girl to take into a private booth, away from prying eyes where I could sit back and have her all to myself.
It's a bit more difficult to find a couple on cam who you want to watch have sex.
But it definitely can be done and I have had some very good couples cam experiences.
Now, I will say that the vast majority of my porn collection is hardcore rather than solo.
