First off, cut the web chat language and start writing regular english. It is much easier to read, and it is much easier to help you out.
There is absolutely no reason why you should write here in that way. Write as you do in school.
When it comes to your problem, you should really start talking to your girl. Honestly if you re doing the stuff you do, I think you re ready to start talking about them too.
My gf was shy and didn't want to "recognise" herself being "turned on". But i started to talk to her about it, and asking her questions about values, and about her feelings.
First he was embarrased talking about it, but slowly she started to act more natrual about it, and today she can talk about it with me.
You know, you don't have to start talking about your erection, and such stuff. Instead start talking about the things you do, and ask her what she feels about it. Be a listner. If she asks you questions, be honest and tell her what you feel. That way you cut the "details" and start focusing on eachother.
When the time comes you'll be able to talk about details, and you'll be able to joke about them etc. But take it slow, and be a good listner, show her that she can trust you with her intimacy.
That's how you can do.
I doub't that she will think you re weird.
Those things that you do, aren't unusual or weird in any way, whatsoever.
