Older guys, unwittingly, can incite too much Dad/Grampa baggage in the provider just by showing up, so don't take it personally. Age happens.
You eat pussy like a world champeen, make sure they get theirs and pick your under 30's carefully, pay your bill, bring your sense of humor, you'll be OK.
And if you get that no-go vibe, tip them, be polite but honest, and leave. No reason to drag out a bummer. Don't rail on them in COED for not clicking, just let it go and try elsewhere. You could even send them a communication saying "sorry it didn't work out, are we cool?". No harm no foul.
If it will make you feel any better, remember...everybody gets old sometime!
I could still get a hard on in my forties, so Fuck you SD, you're a mere child!
Don't RTM that, that was bro to bro not a blow to bro insult!!!
