medectophilia
Medectophalia is the excessive sexual desire for viewing the underlying shape of the penis in the crotch region of another person’s clothing. Getting one’s rocks off on moose knuckle in trousers and/or the imprint of tumescent man flesh in sweat pants (preferably grey). It is the exact opposite of medectophobia, the fear of such.
Gina's medectophilia was most evident whenever Dean lounged around the house in his sweats.
