Is pleasuring one's senses moral

The answer is a yes and a no. An example situation is watching porn.

Under moral sensism, which states that pleasuring one's senses to be moral, doing such as can be considered to be moral because you are pleasuring your senses, but under other moral philosophy, such act is immoral.

Thus, moral sensism is not a good basis for one's norm of morality. It has it's flaws and defects when one would over look at it in the scheme of philosophies such that is is somehow one sided as egoism (satisfaction for one's self) and can eliminate people of the right conscience.

More over, moral sensism can be a good norm of morality when dealt with other moral philosophies and when one's conscience is right.
