Ikr, he's still giving him sex. Like it's not services were not rendered. Heck, if he'd sought a normal prostitute it would still cost an arm and a leg.
The "I feel guilty because I'm not a qualified professional sex teacher" makes me laugh more than anything. Like, are there credentials for that? It's not like you lied and said you were a doctor when you weren't and then operated on him.
You said you could teach him sex and you are, to the best of your abilities. So... he's still getting sex. And good tips on what to do better. I don't see the issue here.
Why is he feeling guilty when he is legitimately teaching him properly? He hasn’t lied at all.
