Blindfolds are fun, not going to lie. Ear muffs are good too. It takes away from 2 of the major senses and allows for heightened pleasure elsewhere.
We have a "sex position bible" that has a few hundred different positions with color images of a real couple doing them. It's really nice. We've tried a lot of them and it's really just a great thing to use or have when we get bored and say "HEY! Lets pick a random page tonight"
Ian(My fiancee) and I bought a sex board game. It's odd but REALLY really cute. It leads to a lot of frisky fun. I'll have to find it and tell you the name. Hell, even if you just play strip poker or naked twister or something like that, it can be really fun and exciting.
Sex toys are great in moderation. Even if that means something as simple as a feather duster, or a small finger vibe. Beginner nipple clamps or some different textured fabrics. Sensation play while blind folded can be some of the sexiest most enjoyable experiences ever.
I am pretty active in the public bdsm/sexual community of my area, plus I own and run a sex toy business. If you have any questions that you want to ask me personally, please feel free. I love helping people
