My pawg GF (25F) gets hit on by so many guys and I’m starting to like it. Nude beach story

Tbh the only reason I am on this sub is because I do not know what to do with how horny this makes me. My long term GF is a slim, very thick, brunette pawg. Over the years she has been on a very adamant “booty building” type kick and loves to show it off. Whether it’s to me, our friends, strangers, it does not matter. A few weeks ago we were at a bar and a group of college guys essentially surrounded her and began hitting on her. For the first time ever I didn’t pretend like it pissed me off, I just let it happen. She seemed to really be enjoying herself although nothing really came of it. I’ve been hinting about a trip to the nude beach for a long time and she randomly last weekend was all for it. We went and i was hard as a rock the entire time. It was packed and she just strutted up and down the beach for nearly 3 hours. A couple guys even approached us and talked to her right in front of me, one of them happened to be extremely well endowed, as am I (pointless context?), and began to get hard. She even commented to me along the lines of “he was fucking huge” and it drove me crazy. An infuriating mix of anger and sexual tension I’ve never experienced before. We even walked the beach together and a few guys ended up walking behind us like dogs. I loved and hated every second of it. A few nights ago she asked me what I thought about opening a Reddit account to start posting ourselves (she doesnt know I occasionally open one for porn although we watch together at times). She obviously is beginning to enjoy showing off and I’m suspecting she knows I enjoy it too. What does this mean? Idk what to do now.
