My problem is that I don't know if the things I do are moral or not. And I think this situation was somewhat caused by reading philosophy.
I grew up in a religious, traditional and sex-negative environment. I don't believe in many of the things that I learned in my childhood, but I guess they have shaped my moral sentiment. Now, for instance, is it immoral to get some sexual pleasure from watching an attractive actress? My moral sentiment says it is wrong to do that. But rationality tells me that I can't be sure about that. In Kant's system it may be wrong, but Peter Singer would possibly say it is OK.
How can I choose a suitable ethical system for daily life? Should I ignore or resist my internal moral compass which is affected by my upbringing? Thank you.
