Crazy Wild Sex.

My boyfriend is only the second person I've ever had sex with me and the first person I had sex with were both virgins so obviously we were a little inexperienced. My boyfriend has had 11 partners and he has been hinting that out sex life is getting a little redundant I want to spice things up but I have no idea what to do I need tips or suggestions of what you guys do, sorry if this is personal for you guys but I really want to make sex more pleasurable for him considering he already has a high expectation I would love so new positions or ideas of how to make thing overall better for our sex life.
