Dumb questions for 'her' 1st time

53, just about to be 54, married but never had s3x (don't know if the ok to write the actual word or not) before coz of circumstances which led to platonic relationship for more than 20 yrs. No touch & feel or cuddles either.

Had a perfect body till about an year ago. Perimenopause and complete apathy towards self has left the body not look as good as then. Apathy was also as a result of giving up on any hope of ever having someone to even touch and feel it, no matter how much the heart longed for it all along. Just a couple of stretch marks have also appeared in the last few months.

Suddenly got interested in a much younger neighbor who too has mutual hots. Morally wrong, yes, but don't mind going all the way if he wants it & when a physical meet becomes possible. It's not something that can be asked for guidance from friends etc coz of the precarious situation, nor something that can be googled. Hence asking here - how to go about it? Does the whole pelvic region need hair removal? If kept trimmed like always, would it feel sharp to him & prick him? Due to perimenopause, sometimes there's some bulging also down there; would it be uncomfortable for him or for either? If he's wearing c0nd0m, would there be still any need for taking any more precautions? If yes, what? Any other pointers pl?

Thank you so much in advance.
