30 times is kind of a lot. You should understand how people are with dating and love. Thing is, if he rejected you the first and second time, the answer will most likely be no the other times
30 times of being told no from one guy only suggests one may have stalker tendencies!
30 times being told no by 30 different guys suggests one may be quite fickle and or desperate or skanky. (Unless your like 60 or 90... then you go girl! You still got it!)
Um try everyday for the past 10 years :D
