A sissy slut, or sissy-slut, like a shemale, is a cross dressing man who usually has breasts and still has his penis intact. Although, unlike a shemale, his breasts are a product of in taking estrogen instead of surgery, and his libido is extremely low due to the estrogen (unlike the shemale, who's penis can still get erect). They are also extremely submissive and enjoy being dominated by both men and women (even though men is more common). They are most commonly portrayed in pornography.
