Agree with Jacquelyne... even *some* trimming is nice. Doesn't need to be totally bare, but a trim for up top & a closer trim for the boys is nice. Especially if you enjoy your partner spending time down there... makes things nicer for her, & in turn, for you.

Plus, when we girls are doing things like Brazilian waxes & laser hair removal to keep the yard tidy, it's sort of nice to have that effort reciprocated a bit, lol. 'Course, you taking a trimmer to it isn't painful (unlike waxing or lasers) but hey, it's the thought that counts, & we do appreciate that sort of thing.
