My boyfriend wants to change the fact that he can't control his arousal around bikinis, what can we do?
Okay, so we've been together for 4 years and for a while we've been noticing something that affects him. Basically, whenever he's in situations where there are women in bikinis (whether it's the beach, pool, or even seeing stuff on social media, etc) he gets really turned on involuntarily. It's not like he's attracted to the people themselves, but seeing bikinis just triggers this sexual reaction that he can't control, and it frustrates him so much.
What worries me is that he's aware of what's happening and that exhausts him. He says he can't even enjoy going to the beach because he's constantly trying to hold back or avoid these feelings. Like he's always in "control mode" and it drains him, so It's frustrating for him because he just wants to relax and have fun while being at the beach.
We both think this comes from watching Piranha 3D a bunch of times when he was a kid cause that movie has so many sexualized bikini scenes mixed with gore that just got stuck in his brain during his childhood. He's been in psychological therapy for other stuff but never really addressed the sexual side in those sessions.
He genuinely wants to change this and I want to support him, but honestly I don't know where to even start. Has anyone else gone through something like this? Does this have a name? Should he look for a sex therapist? Is there anything we can do to help him manage it better? Any replies are welcome, and btw my main language isn't english so i apologize for my bad english.
