So much here that is absolutely spot-on.

Many women withhold themselves from receiving oral.

Some withhold from giving it... never again will I put up with that.

One of the smarter investments I've made recently was Manscaped-brand Ball Deodorant. Does what it says.

My toughest challenge was learning how to ask for it / invite it / set things up so it would fucking happen. I haven't been single in a while but I think I'd drop a hint somewhere during verbal foreplay, and if it's subtle enough (fellas you can almost not be too subtle), she'll respond with an equally subtle affirmation....and when that happens, acknowledge the affirmation then change the subject. The arrow is now in the quiver. More art than science.
