he gained popularity with his tik cocks; that was impressive. but eventually that grew old, and others were successfully imitating him. then he found himself an equally fit boyfriend whom he did collabs with. I thought that was his peak. sadly they later broke up and since then he hasn't done any duo content.
I'm sure there is no shortage of people willing to collab with him, so I suspect this is down to personal preference on his part. this is ultimately his decision and I am not critiquing it, but it does mean that he is running out of options for what his channel shows. personally, I was never that into the whole 'step brother' thing, especially when it was really just one person (himself)
I remember reading that he managed to buy himself a house with his initial OF earnings, good on him. I think it's unlikely he is earning that same amount as before, unless it is all through custom videos. hopefully he has a decent amount of savings from it all.
