Other ideas include lingerie, a sexy outfit or something else that you like wearing that both of you enjoy.
Ideally, your man should be able to see your whole body if you are using HD webcams and big computer screens.
So higher quality pictures are what you should be aiming for.
Thankfully most new computers (Apple, Dell, IBM, HP, etc.) have high quality webcams built in.
Like I always say, men are mostly turned on visually.
You can do this by making your computer screen a little brighter than usual and turning off the main light in your room.
If you need more light, then just put a lamp behind your camera and focus it on you.
Of course, as exciting as Skype sex can be, it can be daunting for people who haven't tried it. Skype sex should be as personalized as real-life sex, which means it can be whatever you want to make it.
Also, considering the horrible prevalence of revenge porn, it's important to know that you shouldn't do anything you're not 100% comfortable with (like showing your face or getting completely nude).
