It is most definitely weird. Women naturally seek older men--older men have proven that they have what it takes to survive: they have established resources, experience, and knowledge (sometimes), which are qualities females naturally look for in males for protection and provision. It is out of the ordinary for women your age to desire younger men, for sure. But, I love that. I love people who can go against their instincts. For instance, males who dedicate their entire lives to one woman when they're biologically built to fuck 80% of the female population; and women who sacrifice for men.
It depends on which racial group and where you live. Most people in the U. S. would be fine with it, I think. Even in the south. Texas doesn't give a fuck. At least, nearer major cities most people don't care about race, much at all. There are still some problems, but not as many as people usually say about the south.
That said. It's not unacceptable in even society's eyes. No one is going to care much. They might be like, "Oh, that's a bit odd." But nothing more than that. They won't condemn you for it. The vast majority of people, at least. And, if you like him what's to stop you from going for him?

I dated a younger guy. I didn't know it, since we started talking randomly while waiting in line one day. He was smart, funny and looked nice (dressed well and had good hygiene). We had so much in common, it was crazy! We decided to go grab some tea, and we talked for hours. Then we decided to go to the movies together that weekend.
I was dating him for a few months before he told me he turned 18 the week before he met me. I was totally shocked. He was a freshman at university and I was about to graduate. He seemed mature and I liked him, but then when then started to get closer to a year together he acted weird.
I never changed my habits, I don't go out drinking or partying. I was always cheerful and upbeat, but supportive when he needed me to be (when he was struggling with mid terms for instance, I helped him). Towards the end, after he asked me to move in with him, like a few days before the move he told me he had feelings for this blonde woman in his class, that was also 18.
Not going to lie, that stung. But we had some good times before that happened.
TL;DR - as long as he's legal and you two get along well, I don't see a problem.
