Too attached...

So I started seeing this guy about a week and a half ago, we've fooled around a bit but never had sex because he gets too nervous that he won't stay hard enough which makes me insecure cause I keep thinking it's my fault. I'm starting to think that I'm get too attached and paranoid. My first and only relationship ended in cheating and lies after 6 years so I get that I'm not going to trust people so easily but I keep thinking he doesn't like me. He seems to like spending time with me and has even spent 4 nights in a row sleeping over at my place. I'm also an idiot because I asked him what we were, dating or relationship, I later apologized for asking so early. He still talks to me everyday over Skype messaging but I keep getting paranoid when he doesn't answer right away. How do I detach myself a little bit in my situation?
