You can sell affiliate stuff if you did not use the stuff but a high, high, high, really high level of clarity is required to do this. Most bloggers lack this clarity. I recall Tony Robbins selling/being an affiliate for a $25K coaching class. Never took it. Never sat in it. But the guy made millions. He had full clarity in selling without seeing. So he rocked out the selling.

A sound product strategy is a must for new affiliate marketers. Ideally, you should choose a niche that you can make money online with and has a lot of product vendors. This will give you a wide selection of products to offer your online community. However, limit yourself to two or three products at a time, so that you become the expert others turn to and trust when reaching for their wallet.
If you have pop-ups and optins on every page, I would have to think that it would be a lot harder to convince someone to link to it. Especially since the pages where you have your optins (and probably receive the most traffic) are probably the same pages that you have your best content on as well that you'd be hoping to pitch in your outreach campaign.
