Should I(20F) pursue a relationship with a guy (27 M) even though I'm not attracted to him physically?

So as the title says...

I have been talking with a guy I met online for approx. A month.He stays in another city(very far) We vibe really well. He's so charming and really everything I want in a man.

But I don't feel attracted to him, he's not that good looking. I never thought I would be posting something about this. I wasn't the type to count looks over anything. But recently, when I got into this dating game. I feel manipulated. Whatever.

So I haven't met this guy in person all from pics, he's understanding and says he loves me(even though we haven't met). He wants to marry me too?. Idk it weird I also feel it's too fast. And lemme tell you i cleared it that I will think about dating after we meet.

What if he's really the genuine person? What if I'm still not attracted to his looks but miss out on the opportunity of getting a good guy?

Any advices would help. If you have dated someone who wasn't attractive, what's ur experience.
