Social media

I know some women in here are older and some are younger some come with knowledge some come with judgement. I just have to ask….my boyfriend is 28 and it grosses me out that he likes 19 year old girls pictures on Instagram. Does anyone else find it kinda weird? Don’t get me wrong, my mans is great. He’s so good to me, but like…I just find it creepy. They’re still teenagers regardless if they’re legal or not. I get everyone has their way with relationships and some people don’t care. People can say it’s because I’m insecure but it’s not that in my mind. I think it’s disrespectful towards me and like I said, it’s just gross to me. Idk. What are y’all’s thoughts? Any similar situations?
