<human>: Can you provide a brief rundown of the text in within 3 sentences?

I'm 26, and I've never dated before. I've been asked out and even pursued on a few occasions, but I declined because I wasn't romantically interested in them. Recently, my friends got me thinking that a part of me will never "grow up" without having had any relationship experience. They think I haven't liked guys (or girls) before because I put up a wall around me when it comes to dating. 

My friends are getting married, and some have children. My coworkers don't approve of my self-proclaimed asexuality and worry that I'll become a "spinster." If it weren't for the pressure to "put myself out there," I would be more than content to be as I am right now. Still, I don't like to admit, "Yes, I'm old enough to get married but have never gone out with anyone before," and be judged for it.

That said, someone just asked me out on a date. I'm not romantically interested in him, just as I've never been attracted to anyone else before. He's a little quirky, but he's nice. Is there a chance that I might feel differently if I say yes, or would I be setting myself up for a mess that I can prevent by saying no?
<bot>: Worried that choosing to be perpetually single is wrong. Asked out on a date by a guy I'm not interested in. Should I give it a chance? Is it fair to the guy who asked?
