adj.
Reflecting or producing sexual desire or behavior esp. that is considered indecent or obscene (lewd and lascivious behavior).

Personally I just find that erotic and do not see emphasis on the pubic region. Though when your sitting in that church like structure reffered to as a court, in some hot humid southern state. They will bring out the good old dictionary on ones ass and clearly point out that not only is homosexuallity indecent but it is also obscene thus clearly making it lascivious.
