What about offering a shoulder rub when she seems tense? The worse that can happen is she will say, "NO." You've endured way worse than that!!

A non-sexual shoulder rub seems like mid-way between a sexual touch and friendly tension reducer. IDK.

Having her brush her hair seems a bit...?? Unmanly? No offense.

Now, if someone offered to brush MY hair. I'd be ALLL OVER THAT!
