Is it normal to have given up on girls even though they like me?

Ok i'm almost 25 and still have never had sex. This kid who used to bully me and beta me up when i was younger because i wanted a girlfriend finally apologised to me. I haven't processed the feeling fully and i don't know what to feel of the apology but it feels good i guess. Anyway I've tried online dating but it never works out too well as i get rejected and ignored because of my race. I've arranged to meet up with a few girls and they seem keen but this doesn't make me as happy as it should.

In real life girls find me attractive and they always seem to get nervous when im near them. They are also very receptive and talk with really high pitched voices and are not mean at all plus they always smile but im still terrified and i don't feel good enough for a girlfriend. I have problems presenting myself confidently and believing that girl could even like me and wanna be near me.

I don't know what to do about this and all the girls seem to have boyfriends. I don't wanna die alone never having had sex but i fear this will happen as i literally just freeze and get awkward around girls which definitely puts them off.

I just can't get past high school cos i still see myself as a weak scrawny kid and not a man. What can i do???
