Let's spicy it up!

Alright ladies we are all grown here. At least I think most of us are!(lol) but, I really want to spice up my sex life with my boyfriend. Me and we both enjoy sex.but you know when you have sex with someone for a while or you're in a relationship with someone for a while things can get kind of boring or you just don't know what to do anymore to make it fun. I would love to try some new things with him that I've never tried before instead of the same O same O maybe some ideas would be nice are even some advice would be nice. Thanks
