Why do creepy old men like me?

I am a 21 year old female and men that in their late 30s to late 50s always try to hit on me. It's getting to the point where I hate going anywhere alone. It's always men that work at minimum wage jobs or don't have anything going for them. And they're creepy; one guy brought me food to work the other day( I do not know him). And another time this guy told me the fact me and his son was the same age was hot. I just don't see myself dating anyone that's almost as old as my parents. I do not lead these men on in any way possible. And the funny thing about it is that I'm lesbian. I don't dress provocatively or like a grandma(I'm more of sweatpants,hoodie, jeans, and t shirt type of girl). Why do the older men try to date me? And why do they always say sexual stuff towards me?(ex. When I turned 18, this guy told me that he couldn't believe I'm 18 and that I should be blessed that I met him (the guy was 45 years old)). Any tips or ideas to try to stop older men from doing this to me? I feel like I'm going to be a future rape victim the way these men talk to me.

Why do creepy old men like you? Easy! Because you're 21. And undoubtedly, because you're (non-obviously/non-stereotypically) a lesbian. Next question? :-) But seriously - can you work out what I mean when I say that, if I add that you should consider what you possess AND lack compared to women their own age, stage and experiences, i.e. what benefits these differences might bring them in the context of a relationship, whether long-term or quickie, and what that might say about what's wrong or unhealthy about THEM and their attitude towards females generally? And can you then work out why your 'lesbian aura' might 'mis'-appeal to men like this?

If they like u than its their problem. Don't worry about them.And anyone misbehaves than kick his ass.As simple as that .:)
