Although most people's first thought when sex toys are mentioned is of sex toys being used in solo play, more and more couples are discovering that adding a sex toy or two to their sex play can help to spice things up. 

It's a myth that sex toys are only for when you're single, or only for when things are not going well for a couple.  This latter use is where the euphemism "marital aids" comes from – the idea being that you need something extra to fix a broken relationship or sex life.  But nothing could be further from the truth..  You can use sex toys at  any time, and you shouldn't feel bad about doing so – any more than you'd feel bad about trying a dish you'd never eaten before at a restaurant.

Sexy costumes and erotic games are a fun way to do this for any couple – they can add a little variety and take you to fun places you might not otherwise think to go.  They're also a good way of introducing sex toys to a relationship, in that they allow couples to experience what sex play can be like with toys to enhance it in a way that is limited – a fine way to find one's level of comfort while still being able to pull the plug if needed.

For couples with a little more experience with sex toys, BDSM toys can be good naughty fun... 

Most of these toys are specifically intended to be used by couples rather than solo, and they can be a lot of fun.  Bondage isn't for everyone, but if it is something you and your partner enjoy, you probably already know how great it can be with the right toys.  Restraints of various sorts, such as handcuffs, leg spreaders, harnesses and nipple clamps, can add to couples play, as can whips and other items used to torment, tickle or tease.

Vibrators, for example, can be used to stimulate nearly any other part of the body during vaginal intercourse, to add to the sensations experienced by one or both partners.  They can be applied to the clitoris, to nipples or to the anus, although nearly anywhere on the body can be fun (just make sure the vibrator is clean first).  Some vibrators, such as the  We-Vibe, are even specifically designed to be used during vaginal sex.

Couples can also experiment with the use of a strap-on dildo by the woman, allowing her to anally penetrate the man.  This practice, sometimes called pegging, has been growing in popularity in recent years, as it can stimulate the prostate of the man, leading to incredible pleasures, while for the woman, it can be interesting and arousing to see what penetration is like from the other side.  (And guys, just because you like it, it doesn't make you gay.  Chill.)

For many of these toys, it's a good idea to keep a ready supply of both condoms and lubricants around, in order to make sure that everything goes smoothly and that toys stay clean.
