Take pictures of each other. Start with something sexy and take it off while he’s got the camera on you. I always make my SO get naked while he’s taking the pictures, so I can watch him grow. It’s very erotic - and it ALWAYS ends in the best sex ever!
Oh yeah, but make sure to use a digital camera. Don’t get pictures developed at Walmart - there could be copies of you all over town!
Download or rent or buy various kinds of porn and look at it together and see if you like any of it. Warning: a lot of porn ain’t all that erotic. It’s very much aimed at guys who are, shall we say, hardened to its effect. But you prolly know that already.
Another thought, starve yourselves sexually in terms of touch and contact for a week. No cuddling when you sleep. None of that hugging, kissing, and lovey-dovey stuff. Then on Friday night watch or read or otherwise experience something you both find sexy, but still no contact – look, don’t touch. Then on Sat. night, you are free to jump each others’ bones.
