What about masturbation/oral with a woman

I wouldn't do either man, they're kind of one in the same hidden behind the real urge which is lust. Focus on controlling your lust and as the brother above said: redirect that energy to something useful instead of wasting it.

This ^^ better to stop it all. Redirect that energy and motivation to things that benefit you

You should not do either you could use it for one or both. I would quit both as they are sins.
