Pretending the toys are a 3rd person is always great.
There are soooo many toys out there to spice up a relationship and I have always said "Save a marriage, buy a sex toy"
Our favorite toys to use in the bedroom is realist dildos and also realistic masturbators like the Cyberskin vibrating ass... Since we own our own online shop we probably have a bit more toys then most people do.
Also sex games are also very great to use to spice things up. Our favorite is 1,000 Sex Games it never gets old lol. Also for smart phone users they have some cool apps for spicing up the sex life.
Also IDK if you get in to any bondage or role play but they have some really good bondage kits for beginners and for the more advanced that gets things hot and heavy.
Role play can be done with out buying anything as well, a few times my husband and I went out to a bar dressed different then what we usually do and pretend that we dont know each other and he trys to pick me up and get me into bed.
I actually find that really hot.
