What do you mean with 'older'?

If you are 20 and you prefer someone aged 32, or are you 20 and you prefer someone aged 55? I can kind of see how a female may be most attracted to men near their prime. And adjusting physical prime at like 27 or so with social status prime, which is later in life, I can see how a female may prefer a man in his 30's, regardless of her own age?

And such a gap would also mellow out more later on.

I don't think you should talk to your parents about this. I would just find someone that's a really good match for you, then introduce him when the time is right.

As someone surrounded by 20 years old and being 33 myself, I fell in love with a 20 year old. If I look at others her age, I still can't imagine how I could fall for someone so young, and I wonder if something is wrong with me.

What's worse is the idea that even if she does like me, her friends and parents may not accept me for my age.
And even I myself, in the back of my mind there is this idea that a girl aged 20 that partners up with someone aged 33; something is wrong with her. I'd know if I was her father or friend, I'd probably voice my dissatisfaction clearly.

Then again, me and her, we are in our same phase of life, I probably barely have more life experience and she will catch me up on that in the next year, and she has probably more experience in relationships by far, and she will probably increase that gap in the next few years to the point where I that it will irk me a bit. And she said she guessed I was 23 max a year and a half ago.

That said, I must say that my position on this is now completely hypocritical.

I don't know how I think we would have handled the age issue if we actually got together. I guess the way I imagine it going perfectly is if she introduced me to her friends/family, they would guess my age a lot lower, the issue wouldn't come up, they would accept me, and then some day they would find out and not care about it anymore.

I did find this idea about there being more woman than one would guess who prefer older men, and that most of them have an older father themselves. I can kind of see this. If your father is clearly a lot older than your BF, it must not be so irking in her mind. If the father and the BF are closer in age than her and the BF, then maybe it really becomes odd at that point.

Anyway, age and aging bothers me now. Never expected that it would. When I fell in love for the first time, with a girl aged 21 when I was 19, I was sure I would never be interested in a younger girl ever again.
