Love that he's trying to hold back a bit, but ngl no. Tell him how you feel over holding it in. I'd rather a bit of a possessive loving partner that only wants what's best for you over a tiptoeing one that is changing his nature to feel secure that he can withstand the relationship and not speaking up about a clear abuse of power and mismanagement of his partner as an employee.
I hope worn out literally means its a romance with my boy getting worn out in the sheets all the time or otherwise ill cry since this is too wholesome
