Again- sometimes it will be accepted and sometimes rejected... Just dont let it effect you if she turns you down...one other thing that comes to my mind- a big hick-up in my own sitch- if you two are together and there is eye contact, be wary of gazing deeply...
I did that SOOO often and it was just plain pathetic...I was letting my feelings show but W was majorly turned off- "why are you staring at me" etc...it made me feel like a creep.
Thats neither here nor there, but be mindful of it...
I say keep with the PDA (pub. display of affect-havent said that since high school...lol)...
If you get serious backlash, just back off, otherwise I think the -"you never used to do that" is a good thing
