I love holding hands during sex. I think it's sweet, and it probably goes along with him being extra sweet, as you said. I suppose if it makes you uncomfortable you should say something, but as long as you like it, it's probably a good thing on both sides.

As for the money, I'd say that's pretty normal. People act different in the beginning of a relationship with most things, including money, and once things get more comfortable there's less of a need to "impress" or whatever
