I wouldn’t worry about if I was you.
I’m currently “dating” an Chinese masseuse, she works in a rub and tug joint we met in!
Doesn’t bother me at all!
She tells me some funny stories, what some men want when behind closed doors is quite shocking!
The other day she told me a man came in, maybe in his 40s, paid for 30 mins, placed £100 on the side table. then pulled out 3 condoms which he rolled all 3 over her fist.
Then got on the table, bent over and lubed up his arsehole, grabbed her arm and pulled her fist inside of him.
