Be natural and respectful, just not rude I'd say.

Don't be afraid to say something that's on your mind as long as it's not going to hurt someone. You'll never know if people will like your or not if you aren't yourself.

If you've had no other partners you're safe from STDs. However just make sure you're both clean, so that neither of you potentially get sick from oral sex is what I would add on to that.

My girlfriend made me a blanket and sent it to me when we were away from each other a few years ago. It was one of the nicest things I've ever received, but it felt special because there was a connection to it. I definitely feel what you're describing.
