uh yeah, I do too
I think you touched on point, though; it's the idea of sending the pix to arouse someone other than your partner, that makes it illicit.
Sorry, I was going on the assumption that this was hypothetically about a typical monogamous relationship. In the real world, showing ones feet could mean anything...or nothing at all.
Have you thought about wrapping your feet in clean unused garbage bags?
It may not be arousing to you but sending images to this person, satisfying their desire, is inappropriate in my opinion
Ummmm yeah ahhhhhhhhh nope-only cause feet do nothing fer meh!hehehehehe
