Well if you can get past most of the worthless posts sometimes there is useful information on here.

Why don't you ask him? What are you worried that he might see?

I would first Follow JP's advice then just for fun search through the most perverted stuff you can find. If he starts introducing some really weird stuff you know he is spying. I would get one of your online friends to help you. Send some stuff saying how bad you want to get another girl into bed with your boyfriend. If anything would entice a man that would be it.

Good Luck and just ignore 95% of the posts on AO and you will be fine.
