Stalked by yuckies

Ok... I only ever seem to attract guys who kinda creep me out! What is with that!Read an earlier blog about the bus stop guy below for an idea of my previous experience with being picked up.Here is another doozy of a story.Ok, we need to rewind to last year. I was walking home from the uni library on a Sunday afternoon. This car pulls up next to me and this guy gets out. I am already a little freaked because this is a quiet-ish st. He comes up to me (I am still walking) and tells me he saw me at the library and followed me (great way to get a positive reaction from me)... he tells me he would like to get to know me better can he have my number. I basically say that I can't give out my number right now, but wanting to get out of the situation I say why don't you give me your email.... he does... then I say I have to go and he offers to drive me home in his car (which spooked me) and I was like no I am fine thanks and said farewell... the whole thing kinda spooked me, I think because of the car and quiet street thing. Plus this guy was quite a big African guy so there was a physical threat consideration as well.So I was at the supermarket tonight in the carpark (kinda deserted location again) and who should come up to me but the same guy! Apparently he saw me at the library once but when he came to find me I was gone. Apparently he thinks of me often and would like to stay in touch. So I say sorry I lost your email last time, and he writes it down again for me. Then he asks how I have been etc (except he asks the same question like three times) and then he asks for my mobile number again, which I don't give away after bad experiences previously so I make up a lame excuse why i can't give him my number. He says he really likes me blah blah and wants to get to know me better.I was kinda spooked again (bad location choices all the time by this guy) but he seems quite harmless. His grasp of English is not terrific though, and he seems considerably older then me (like at least 5 years older). He wasn't ugly or anything at all, but I'm not sure if he is my type.I wish someone would pick me up in a normal non stalker-esque way! Another thing that is playing on my mind is maybe it's because I think that I am not attractive and hence I can't understand why these people are putting moves on me unless they have some kind of sinister motive. Maybe I am the screwed up one... I just don't know!!!!What should I do? Just "be friends"? Via email? He seems to be pushing for something more very quickly.... don't want to lead him on but don't want to be a snobby bitch.But I am getting sick of being 20 and never been kissed, eeek how depressing.
