Camsites that accept male models:
Token Bassed:
Chaturbate
Stripchat
Cam4
Camsoda
Bongacams
Manyvids Live
Private Bassed:
Flirt4Free
Streamate
LiveJasmin
Imlive
I think thats all of them, there might be a few others though.
As for which I would recommend, it's hard to say, different sites market to different audiences so the best bet is to try them and see how you get on. Just be sure to check the % that they payout, some like Flirt4Free are extremely low.
