For an actual answer: I don't know, but I think you are more likely going to hurt yourself if you have never come to understand your own body.

Basically- masturbation can help you understand the effects of friction and lubrication. About how you 'warm up' and get ready for action. Without this understanding, you are going to fit tab A into slot B without getting ready at all- or even knowing that you aren't ready. And as a result, it will end up as a fiasco.

I mean…more a fiasco than usual for your first time. Obviously. It is all relative.
