It is human nature to find people attractive. I don’t think it’s a big issue at all. I would have an issue if my DH was seeking out social media accounts or something like that of people he was attracted to solely for the purpose of ogling. That’s disrespectful. But a passing “oh yes please” sort of comment, to me, is simply passing and I do the same thing!
We don’t feel insecure about how we look compared to celebs for a few reasons.
One is simply rational - neither of us are paid to look good, or have the time and funds to invest in looking good, in the way celebrities do. Achievability of “beauty” endorsed by Celebrity culture is the ultimate con and we all know very well it’s a pile of old rubbish.
The most important reason, in my view, is that we aren’t together for our looks. We love each other for our minds and hearts. We are best friends. I am not the most beautiful woman my DH will ever meet, but I don’t care because my DH isn’t shallow enough to be with me because I’m hot. I am the “whole package” in a way no one else ever will be. The same goes for how I feel about my DH. I might find someone more physically attractive… but that means literally absolutely nothing to me. You might be hot on the outside but you couldn't hold a candle to my DH overall. There’s just no comparison.
It’s like wrapping paper, it may be very pretty but ultimately gets thrown away and the question remains, “what is the gift like?” Real, long lasting attraction is about being attracted to someone as a person rather than as a purely physical entity. It has to be that way or we would all end up alone - We all will get old and grey at some point!
I mean this kindly, OP - it sounds like therapy would be beneficial to work through your insecurities. You are worth investing in to make sure you live your best possible life and don’t have to sit and cry because of something that makes you feel so sad.
