Cockrings are another simple, yet effective toy. They can make orgasms more intense, increase sensitivity - and are helpful for guys who have problems keeping their erection or with premature ejaculation. (A few words of caution: use lube and don't wear one for longer than 20 minutes, tops.)
The next toy I recommend is actually the same one as I recommended for girls in this post - but with a little extra addition. You can actually buy custom cockrings of different shapes, sizes and textures, that actually have a loop designed to hold a bullet vibe (see above). This can be worn on the penis to stimulate both the shaft (and, depending where it's worn, even the testicles) and can be positioned to hit your lady's sweet spot at the same time!
Because you guys have a prostate (or "p-spot" - yes, you guys get cute names too), anal play is a whole different ball game (no pun intended) than it is for the ladies - and if you're open to it, it can be a lot of fun.
And last but not least, don't underestimate the enjoyment that can be had from using toys on your partner. I know some of you guys feel threatened by our toys - but don't worry NOTHING replaces good old fashioned fingers, tongues and, of course, penises. The toys are... like a little extra spice in the sauce. If you play with them with us, I guarantee you'll have fun too!
