i would suggest you figure out whether she's even remotely into kink before springing any of those desires on her. open up discussion. suggest some other, lighter forms of kink/BDSM to gauge her interest. if she's open to those, then you can work more specific interests into the conversations and possibly play. unless you talk to her to find out what she's into and not into, you'll never know. you may be pleasantly surprised. or you'll find out it's not her thing. either way at least you are communicating your wants and desires openly.

Well, if you haven't discussed anything along those lines with her before....start out slow. Maybe get into a discussion of kinky things and see what her reactions are. At least then you'll know if she's open minded, and safe to bring these things up.

With golden showers, why not start out by encouraging her to pee when you are in the shower together. Not on you, at first, just see if she can even pee around another person. My lover is very squicked by peeing in front of anyone. She never leaves the bathroom door open, even if no-one is home. She won't pee if I am in there brushing my teeth or in the bath. So, with her, it is totally out of the question to think she will do golden showers on me. She isn't weirded out if I pee around her, she's just completely not into peeing around anyone else. She doesn't even like it if I talk to her through the door when she is going to the bathroom.

If you can get yer girl to pee in the shower with you, then you can bring up the idea of her peeing on you. The bath is a really good place for such activities anyway, cause they're known to be messy. BTW, if you get her to do it, and she pees on yer face, keep yer eyes closed, cause urine in the eye hurts real bad.

As for strap-on sex, how bout getting her to go to a sex shop with you and then showing her some of the toys that seem interesting to you. Remember about anal sex to start slow and small. Thoughts of a chick wielding a big ole strap on dildo can seem sexy, but in reality, it takes most folks quite a while to work up to something like that. I have plowed several dudes and many have eyes bigger than their anuses.
