You aren't the only one!
I've never been given a guy's number, never been bought a drink at a bar...hell I didn't even get to go on my first date until I was in my late 20s as I was asked out once at 18 and never again (and I stupidly said no at 18!). The first date was arranged through a family friend or it never would have happened! Men just never approached me.
Just before I turned 30, a guy around 40 approached me, introduced himself very politely and asked me if I'd have coffee with him. This was the first time I'd ever been romantically approached by a man and I freaked out and just didn't know how to handle it. Not visibly to him, but I went to the toilet afterwards and my entire face and neck had broken out in red hives! I was totally speechless because I'd just never been used to anyone being interested in me, wanted it for a long time, given up in the end and when someone finally was interested in me I was really spooked!
Other than that. I had a few instances of guys at house parties trying to get me drunk so they could sleep with me but they weren't even remotely nice about it and I only found out after they told friends of their plans.
I'm 40 now, like you married (the relationship came out of a friendship) but I have never had a man tell me he thought I was pretty or anything when I was younger. Apparently they told other people that! And I've enough other people who paid me physical compliments to be objective and say I can't be totally hideous. I used to joke that I'd had marriage proposals from 10 year old boys and 80 year old grandads but couldn't get a single date with a man my own age!
I really had a lot of hang ups about it and still feel sad I was a wall flower/very late bloomer but there just seems to have been something very unapproachable about me. I never felt like I could get male attention and it still gets to me when friends and even my mother boast about all the male attention they had how they essentially had men eating out of the palm of their hand.
My stories all involve handsome men approaching me, looking me in the eye shyly and saying, "Can I ask you a question?",
me getting my hopes up that this was finally it, only to get, "Is your friend single?" and being the one left holding everyone elses bags while they danced with guys, feeling completely unwanted but smiling and putting a brave face on through it all. It was a pretty miserable time and I can't say I've really healed from it to be honest, shallow as that sounds. I still feel like DH did me a massive favour by paying me any attention.
