I agree. A lot of male customers at my job (half of them my dad's age) are attracted to me only because I'm pretty, and before I started changing my image to look less naive and innocent, they would hit on me in the form of teasing and other unwanted comments. (I don't get that so much anymore but I still get stares, which I'm currently fighting.) And there have been a few instances where men have straight up asked me to go out with them. (Fortunately those ones are usually pretty respectful.)
I'm not interested in relationships at all, but even if I were, I wouldn't go out with a complete stranger. I would be friends with them first, get to know them, see if I liked them enough to date them, then go ahead. Another risk of dating someone just because you like their appearance is that however attractive they are doesn't say anything about their personality or character. For example, guys may like my appearance, but if they really got to know me they'd probably be surprised to find I'm autistic, I'm obsessed with Disney characters, I battle anxiety from time to time, and I can have violent meltdowns, to name a few "weird" things. You just don't know who you're dealing with if you only look at their shell.
But then again, I don't think a long-term, meaningful relationship and possibly the lifetime commitment of marriage is what these guys are after. And that makes the whole thing even more superficial.
