Op, I think you are very brave posting about this on here, you are getting a lot of snide and 'who do you think you are' comments about your appearance, about thinking life is a rom com, and just sucking it up.
I don't hear that at all in what you are saying. It's playing on your mind, probably because you are stuck in a lot and your marriage isn't as romantic as it could be, that you haven't really experienced that romance that you were wondering could have been out there for you in your teens and twenties. You got married, eventually, when you pushed a relationship forward, but you don't feel anyone was pushing it along for you, ever.
I have friends like this, I'm thinking of one in particular, actually she's really attractive, but she just didn't know, as someone else on this thread, how to capitalize on that, and she often got overlooked for less conventionally attractive or more confident friends. That led her to marry basically the first guy who paid her some attention who was not a choice catch, if I'm honest, but she has made a good marriage out of this.
Is it wrong to feel wistful about missing out in your teens and twenties, I think it's normal and fine. I had the opposite, I was not amazing looking, but I have been the object of passion and romance and it's fantastic. Not with losers, not with obsessional stalkers, just lovely lovely guys who decided I was really something. I married one of them and that foundation of him thinking I was really 'it' (and me thinking the same about him) has carried us through a heck of a lot of the storms of marriage. In fact, I wouldn't be prepared to get married without that, because I know myself and I know I do value romance over day to day compatibility, I'm prepared to take more downs to get those highs.
I get the feeling that you do feel like you missed out, I don't think it's obsessive or selfish when you have children to contemplate if life might have taken a different turn. Or to want your own husband to be totally in love with you. Not all the time not in all circumstances, but to feel desired and adored, even just occasionally, is a real experience to have in life.
You posted, you got slaughtered over it, called names, hopefully it has made you think a bit though about how you could get some of this romance into your marriage- how could you create that more romantic experience that you want, or perhaps your thoughts are more about how you could get out and try for it, I don't know. I don't think you are wrong to wonder though.
