Some days before, I saw my electric shaver in the bathroom and a few stray fragments of hair still sticking to the edge of the toilet bowl. This was a good sign- it means my wife had just trimmed and shaved.
When I licked her pussy the first time 10 years ago, it was a bit hairier. Over the course of our relationship she has gradually kept it shorter and shorter, to my delight. As positive reinforcement, when I go down on her I have taken to whispering how much I love licking her shaved and how good she tastes. Nonetheless, her priority in hair length seems to be a balance between hygiene and frequency of trimming. Anyway, our sex drive is not as fantastic as some /r/gonewildstories posters, and we don’t do the sexy stuff as often as I think I would like (which is once daily, but even I know I don’t really want to fuck every day). So to expect her to fastidiously keep it shaved is an unfair workload for infrequent sexy-times.
