I just read this entire thread - yeah, I may be trying to get away from work on a Monday morning....
My 2 cents: having two personas is - in my opinion - dumb. You are who you are. People are ABSOLUTELY going to find both personas and then it's just odd.
Just be who you are - a massage guy for those who want that, a sex worker for those who want that, and show what you want on OnlyFans but don't do the 'charge up' thing. Offer to create CUSTOM videos for fans – some guys are into feet, some are into armpits, some people wanna see your nostrils (everyone has their kink) – and they will pay extra to have a custom video made JUST for them. That's the model I have seen that works the best. I agree with the Netflix Trailer analogy. I have signed up for OnlyFans before ONLY to find I had to 'pay 15-20 bucks more to see 'the good stuff'...Nah, I unsubscribed quickly.
