Is self pleasuring/masturbation to images of people you know and care for morally wrong? If not, why?

What you do in your personal, private time isn't anyone else's business.

In general, no, since it doesn't actually harm anyone.  But if you're jerking off to images of young children in the family, you need to go get therapy.

It is acceptable as long as you notify them.  Pictures are not necessary however.

I don't think it is wrong morally or for any other reason. It is a fantasy, dream! Enjoy it baby!

It's opinion but mine is that jackin' off is never WRONG.  Problems come from trying to make some fantasies real.  I can tell you that unless you're fu kin' a particular girl, do NOT tell her that you fantasize about her when you're stokin'.  For men, jackin off is just jackin' off. Women can get really weird about it--even jealous.  So don't tell men that you imagine fu kin' someone you know if there's a chance that he will tell a woman.

depends on your morals not mine
but if your looking at family members that would be wrong

It could be considered 'morally' wrong - but since it's not hurting anyone, then jerk away!

it only becomes a problem if caught in the act

That depends on your point of view.
