I mean, we can imagine a counterfactual where the girl was even more insistant.

“No, anon, you’re taking me on a date! I won’t take no for an answer”

And then they go on a date. Anon is very awkward and has no idea what to do. But at the end of the date, she gives him a bj. Now what?

Well from her perspective, maybe, she did a good deed. She gave him some experience and confidence and set him on his way - hooray!

But from anon’s perspective - being anon - he is in the same position, only worse. After all, for some reason he can’t possibly understand, a girl went on a date with him and blew him, practically handed herself to him on a silver platter, and yet he still managed to fuck it up and didn’t lose his virginity. What a hopeless loser he is (he thinks to himself) - even if he is just given the perfect chance, he must be so repulsive and terrible at sex that no woman will want to touch him once they get close enough.
