@harmonica,
Can you simply ask your partner for what you want?
I am not exactly sure what you mean by "naughty"... are these things that she would do for you if you simply let her know? It is a strip tease? Is it oral sex? Is it sex outside? If something is exciting to me and a partner says "I don't do that" it is kind of a buzzkill. But if she says "I don't know exactly how to do this, but I would like to try".... that is as exciting as hell.
In the BDSM community, there is a ritual that I think is a good idea for everyone (even outside of BDSM). You sit down with a partner and create three lists.
- What are things that I enjoy or would love to try?
- What are things that I may be interested or curious about, but I am not sure I would like?
- What are things that I hate or never want to try?
Then you can have an open conversation, and you can talk about how to have an exciting sex life for both.
I have always found that communication is the key to great sex.
