It seems like both of you are putting in the effort with mininal results, perhaps couples therapy could be an option if you haven't tried it already? Unless you don't deem those two issues serious enough for such an action since you said the relationship is otherwise great. So to what extent do these two issue affect the relationship?

you mention if she has adequate communication skills then the fights would stop. How do these fights begin?

As for the sexual touching. No, I don't think you're being unreasonable. You shouldn't feel guilty because it's likely something out of your control. Particularly if there's no discernable reason as to why you're like that (such as a bad experience)

I also do think it's normal for your gf to respect your boundaries while mourning the fact she can't be touchy feely with you. Again, it might be a preference out of her control and of particular importance to her. It starts to be an issue though if she persists in wanting to do so after being told no multiple times
