GIRLS, I need some insight?

I`m an 19 year old guy who has never had a girlfriend or been in a relationship and of course every friend of mine has. I am not gay but I have never seen the need for a girlfriend in my life. I have had multiple attractive girls ask me out (which is weird and I suppose negates the possibility that I am ugly) but I have only wanted to continue to be good friends with them all. However now that I want to be in a relationship with someone I am afraid that I the girl (whomever it may be) will be highly influenced by my lack of experience in the relationship aspect of life. So is that a reasonable thing to be aware of or is it something I should not worry about
