What is it

I have an asexual friend and I’m crushing on her. I’m not really one hundred percent sure what asexual means since my parents are strict and homophobic so I don’t want to look it up. (This basically the only social network thing that I can use without my parents finding out.) but I think it means someone who doesn’t have sexual feelings for people. (Please tell me if this is wrong cause I don’t really fully know what it is and don’t want to offend anyone!)

So I’m pretty sure that asexual people can be in a relationship but I don’t know if that’s correct either.

So if you know what it is PLEASE EDUCATE ME!! And should I ask her out or will that offend her?

Sorry that I sound like I absolute idiot in this.

Thank you to however tells me! 😁
