(ok, spot the person feeling horny tonight! lol)
Do you get them if you don't have sex for a while?
Do random things set you off?
Do you eye up colleagues to placate your thought?
For me, yes, I end up feeling so god damn horny that it manifests in me sitting there tapping my feet and moving my legs, people in the office must think I'm potty (or need the toilet! lol). And there's a rather lovely lady who works downstairs who is rather easy on the eyes!
