Masturbation is good.
Masturbation is good because it is a pleasurable act with no affect to your health as alchool, drugs or some other activities bring forth.
Of course, it is like scratching. You relieve an urge or a desire without escess which can, in the metaphoric example, hurt your skin where you scratched too much.
When the need is satisfied, you all know that there is no need to scratch further and you know that (like mosquito bits) you can irritate the skin.
So, a little amount with no exaggeration is not unsafe or unpleasant.
Someone can argue that it is a sin but if we are taking into account all the different beliefs, we cannot accept a universal law. It will be only a rule for a restricted group.
Same for the "bad cause of religion" part. There are some religions, probably, which find them as a neutral or even positive act. Even religious or sacred. Who knows?
Is masturbation good with your partner? Yes, i can confirm that and i think that falls into sexual acts,
Is it cheating? I do not think so. I can agree with the "only your other can give you orgasms", because it is a supreme act of devotion that i could not abide but that i respect with almost awe. But i do not agree, better: i strongly disagree with calling it cheating, It is just taking care of yourself and knowing yourself better, something that helpes your relationship. It gives you self awareness of what you like and, expecially, it involves you and in a relationship there are two persons. You and your partner, so no: "you" is not an esternal person to that relationship.
Lastly, i personally disagree with the "not for lady".
It is a glorious personal ecstasy and i dare everyone to look upon the ecstasy of saint theresa (L'estasi di santa teresa), the sculpture from Bernini. Does it look unladylike? Does it look inelegant? Does that self mind pleasure seem to evoke scorn?
But i think there are persons, here, which think that and i do not think this is an opinion on which we can argue.
This is a ideal "form of the world". A founding value.
There are those who think that elegance and etiquette are something and there are those who thin differently.
As much as i criticize the "rule and role of religion" because it is a system created by others and imposed by sociaty as a tradition which likes to condemn others even when others do not partake in that beliefs, what a person comes to reason with his individual mind and the way that single person sees the world i cannot condemn.
I support that.
I can debate the doption of systems created by others, but i have not the will nor the right to challenge a personal vision of the world.
