Help need perspective?

I am 26 and have been with my partner for 2 years. He is really wanting to create his own business and is creating websites here there and everywhere. He is very driven and wants to have a better life so we can be financially secure. We have generally a good relationship and are generally happy. Recently though he has been glued to his computer and has so many ideas and ways to make money I can't keep up! His latest idea is a porn website which would automatically collect videos without much effort and wouldn't have to do much work on it. I feel uncomfortable about this, I just don't want to be linked to something like that even though I have watched porn and been previously okay with it, am I being hypocritical? We spoke about it and he said he would keep it quiet because he wants to build a good name for himself and would probably end up selling it. He said he wants to test out this idea because it could be profitable and he said that I am coming from a view that has been drilled into me by my mother (who is very frigid and would not approve of such a thing). He said my arguments against it don't really make sense which they don't but all I know is it makes me feel uncomfortable. Could some one give me some perspective on this?
