It's hard to say with so minimal details... What would you like to try or what would be "fun" to you? Are you seeking a partner for RL or online play? Or do you already have a partner & want to try experimenting with them? Have you ever tried anything "semi normal" before? What are the things that appeals to you or would like to try?
Well, don't just bring home a huge vibrator and expect him to use it on you. Tell him straight on you wat to spice it up a bit and then suggest toys, maybe letting him tie you to the bed...
I've always found sexual role playing very exciting. You can go all out with wigs and costumes. It is so much fun! It's like making love to someone new and exciting and being with the person you love at the same time.
With role play too it can be easy to ease yourself into it as well with a simple little "Oooh, I've been naughty...What are you gonna do about it?" Hehe see how he takes it. Who knows you might find he's into it then you can build from there into "deeper" roles.
