Yes, I usually do, mostly in front of a mirror. I have very beautiful legs, watching my legs turns me on, particularly when I wear black stockings.
I do prefer it, but sometimes I'll just pull it out if it's a quickie. I love cumming on my own thighs!
When possible….YES! I like being naked any time. But most definitely when indulging in self pleasure.
Always! As a nudist that hates clothes especially while masturbating. I could never imagine pulling through a zipper
I'm always naked when I masturbate except when in a non-secluded place outside (in the garden). Then, I'll wear my bathrobe fully open if that's where I choose to cum or I'll remove it if I have chosen to stand or lay down in a secluded place.
Naked is the best! Especially when reading the hip forums. It's like edging, I try to take my time before giving in and making g myself cum.
