Escorting is a different issue entirely. Aside from the fact that it's illegal and has a chance of giving the john an STD, it's not relevant to involuntary celibacy because the primary issue is relationship dynamics (or the lack thereof), not transactional sex.

The ratio of man to woman may be the same, but that doesn't mean one man can't have several women and constantly juggle them as "friends with benefits," which in all likelihood appears to be what's happening based on the disparity between male and female celibacy rates.
