Hello! I'm looking for a PB line (slash pls) with this male porn star (A) against a character (B) who is markedly less experienced (even hesitant) because of bad past experiences with past lovers. For whatever reason, they go on a date together that goes remarkably well and have amazing chemistry, but it ends in a horrible attempt at sex where everything imaginable just goes wrong (maybe B is anxious because A is an incredibly hot porn star, has never really had good sex, etc). B thinks he's no good at sex, but in reality he's just had a string of terrible partners. B works up the nerve to ask A to teach him how to be a good lover. A is a bit infatuated with and endeared by B, and he resolves to show B that sex doesn't have to be horrible / painful and can actually be really fucking good.
Ideally I'm looking for something a bit cute and romantic, but not without drama. Humor especially is A+, a comedy-of-errors style scenario where they don't take themselves too seriously and the sex is imperfect, that morphs into something deeper and more meaningful. If Hemsworth is a dealbreaker, I'm also happy to take PB suggestions.
