Is it ever morally justified to impose your will on someone for the sake of personal gratification?

It's never morally justifiable to "impose your will" on another person because you think they're hot/for personal gratification. That sounds a lot like making the end justify the means - and abusing another in the process.

"Morally justified" and "impose your will" just don't belong together in the same sentence!

Forcing yourself on someone, especially and particularly if you think they're "really, really hot", is WAY out of line. In some places it could even be called assault, sexual assault or rape, depending on how far you get.

And imposing yourself on someone else for "personal gratification" is definitely NOT moral!

True, not everyone in the world IS a heartless monster. Some people are simply egoistic jerks. And many people take others' feelings, needs and desires into consideration and don't try to railroad, browbeat or otherwise force them into submission.

Did you really try to come up with a euphemism for sexual assault?

You know the answer to your question. It is NEVER morally right. If you are unable to get them to go out with you or to seduce them by their own free will, give up.

(And maybe not everyone in the world is a heartless monster...but the fact that you had to think twice about your question leads me to believe you might be)

No, you cannot deprive someone of their freedom of choice, that is, not impose your will for your personal gratification. If you do, you are breaking the law and committing violence against the person. In fact what you're doing in denying their rights, is treating them like an object for self pleasure. You're not having a normal relationship with them. Don't even go there.

well stated question, and The answer is No! not ever... unless maybe you save someone's life and they were suicidal. This indicates that you have a conscience- which is good... act on it and maybe your life will benefit from it...
