<human>: Can you provide a brief overview of the text?

Hi,
So roughly 6-7 months ago I found out my GF (We were together for 7 years) was cheating on me. I found out through some circumstances and even posted on here around then talking about it got a lot of support etc and I even listened to you guys I left her went no contact etc. Honestly It was a blessing having you guys there to help and even had some people reach out and share their experiences and Pm'd me. Just to have someone to talk to anonymously was nice. 

So fast forward to now, I've been somewhat seeing a girl. I really like her she is great. We go on dates (zoo, brewery tour etc.) Awesome. That part is great I enjoy hanging out with her but my concern lies in the fact that since everything happened with my ex who I was intimate with (she was my only partner the only person I even kissed if we're being honest here up until that point) I'm like not interested in being intimate with anyone sexually. I went home with someone after the bars one night and… it was awful. I didn't enjoy it. What I'm trying to ask is is this normal. Do people go through this? I don't want to be unfair to this girl I'm hanging out with now because I know she likes me and there have been moments where these things above may have happened but they didn't. It's not that she isn't attractive either she is gorgeous. 

I just don't want to be unfair to her.  At the same time I don't want to talk to her if she is going to think I still have feelings for my ex because I don't. I just really like this girl but I'm afraid this is going to mess it up or maybe I'm just not ready for something like this. I really don't know what you guys can tell me but I wanted to at least get this out here and see if what I'm feeling is normal for some people and what your opinion is. My guess is people are going to tell me I need to be open and tell her about it (not as easy as it might seem).
<bot>: ex cheated on me a while back we broke up. Seeing new girl and mentally it's hard for me to be intimate with anyone on a physical level. Is it normal if not what does it mean.
