Does your domain have value? No. Almost no adult "domain" has value like those in mainstream because most adult domains are purchased based on the value of the traffic or any unique content you may have.
I will however tell you where you went wrong so you don't make this mistake again. First and foremost you can't blame your lazy friend simply because in this business you have to learn to depend on yourself. Consider him a wash, notify him that you are severing all ties to him because he is a lazy bastard and just do it yourself.
Also you say that you did the research but clearly not the readily available research on how to search engine optimize your blog. With out SEO you probably won't ever draw in the kind of traffic you need to make any money. Researching this should be your #1 priority and the information about SEO for your blog is really easy to find, just use google.
Next problem is that you don't have any value added content. Google rules state that they have no problem using affiliate content, but you must also have something valuable that makes your site unique and not like the other 200 zillion people using that same content.
You need to give that some serious consideration because what if your SEO research does very well and you get high listings in Google based on your desired keywords? Any smuck could then report you as "spam" and you run the risk of getting knocked down from the top spots as a result and less traffic means less money.
Improving the quality of your site isn't the #1 priority, but it's something you will want to consider for the future. For now, learn what you can and don't be afraid to ask for help when you need it here at GFY. I know that some of these guys tend to joke around a lot but that's what makes this place unique.
There is also a lot of help out there too, so don't be afraid to take advantage of it.
**** edit:
Sorry one last thing, the LeapFish.com thing was a joke. LeapFish.com always EXTREMELY over values a domain. If you are not familiar with the valuation of domains then you wouldn't really have known that. For example, check out the value of all4u.com on LeapFish.com.
