Hypnosis won't help you here unless she herself wants to like these things more and is willing to work with you.
>"As stupid as it sounds I really care about her feelings"
The only thing that sounds stupid is you trying to force her to do something that makes her feel horrible.
If you want to do this the right way, you ease your girlfriend into it, start with small things and work your way up slowly at a pace she is comfortable with. Show her how much it turns you on, what you like about it. Show interest in her needs as well, go outside of your own comfort zone for her. Put as much into the relationship as you're getting out of it, if not more. Then you might make some progress.
If it seems like she will never be as into it as you like, and you can't handle a relationship without that dynamic, be upfront about it with her. Don't try to force a person to change to meet your needs, it will never work. At best your ass is going to get dumped, at worst you'll end up a registered sex offender with a restraining order and prison time.
