<human>: Can you summarize the given text in a few sentences?

We have been getting along really well, but there are some hiccups. From her side I'm her first boyfriend, so she doesn't totally know how to handle things, which is alright but she often worries about how I've had other people and doesn't like to talk about it, how do I convey that I like her and no one else, I've explained it but either she gets weirded out or she doesn't understand. She also has had trouble with anorexia, so eating foods with her or her being naked is a problem with her, how do I get over that with her or ideas on ways to alleviate it.

 Finally from my side, I have more trouble with the sexual aspect of our relationship, honestly shes so pretty and beautiful that I get extremely nervous or I just want her to enjoy herself so much that I can't keep an erection, so then I get even more nervous and it compounds over several weeks. I also have problems with believing its real, like I seriously stress often about whether shes gonna dump me, when she really loves me and has personally said she wouldn't, we even have plans for the future and I still stress CONSTANTLY about it to the point of breaking down crying about it.
<bot>: She has anorexia/first time issues, I have performance/anxiety issues, Mehh help me please!
