yes I'm from a different generation or 2, or 3....but you said you need an emotional connection for sex to happen....you said you had performance problems in the past....just going from that.
I think it's plenty....maybe 13 hour too much for me ... but clearly not for you ....I don't know if 15hrs over week or 2 eight hr days????...No frame of reference. I'm not the one with this problem....YET
I'd call the DR and ask ...don't waste the money on the office visit. I don't think they'd care about writing that at your age. Or if you're in there for another matter ask for it worst case says no or wants additional tests. ...ching the bill on ya.
