Aitah for thinking about other guy while in a relationship?

I (22) have been with my boyfriend (24) for over 2 years now. Honestly, he’s the best thing that happened to me. He showed me what a real love feels like, no toxicity, no hot-cold stages just love, support and a healthy relationship. The only issue is we dont get to see each other as often as we’d like causes we are doing semi distance relationship. But we have completely different life styles. Him waking up around noon and going to sleep super late (4-5am), doesn’t workout (but he still looks good i don’t know how), working morning and night shifts… and me living that healthy life 7-8h of sleep, going to the gym, working 9-5 job… So I’ve been going to the gym for about for about 3 years, and a gym i go to has separated women and men sections. And for a long time i was only in girls section, becausei was terrified of a men section. But recently i picked up a courage and moved to men section cause of better equipment. Everything was fine until i noticed some of the guys staring at me. Ar first i didn’t think much of it, they were probably just confused why is the girl willingly in their area or whatever. Then i started seeing all the same guys cause our gym is not that big and its in a pretty small neighborhood. But there is this guy i dont know anything about, no name, no age, nothing. He’s okay looking but has some really bih back im talking like dorito shaped back. And every time we are in a gym at the same time he is looking at me. Doesn’t matter where i am or where he is, he’s looking. Passing me-looking, we are on a different side of the gym he is looking for me, if i happen to workout somewhere behind him he is looking in the mirror behind him. We never had a conversation or anything, the only interactions were “are you using those”, “how many sets do you have” etc. its not that im attracted to him or anything, but im thinking about him on a daily basis. Honestly just thinking about the way he’s looking at me. And i fear im starting to like those stolen glances. So aitah for enjoying “the attention” the guy from gym is giving me?
