Do you think it would be uncomfortable for my ex friends with benefits to be my personal trainer?

He just started training all of my roommates at the park. My roommates don't know we were friends with benefits. They were the ones that asked him if he could (they put me in the group chat as well so it's not like I am not invited).

Anyways, do you think it would be at all awkward or uncomfortable for us? We are just friends now. But honestly I think if I saw him working out id be very turned on and attracted towards him. Also, don't personal trainers have to touch your body at times in order to instruct you?

what do you think he would think of me joining next time?

do u think this is something I should avoid or just have fun with?
