The bend-over-boyfriend sex position is a doggy-style sex position that puts the male participant on all fours with the help of a prop. The position offers a range of possibilities, including, bondage, teasing and anal sex (in this case, using a strap on harness).
The prop helps to provide comfort and stability for longer bouts of play. Heterosexual partners may swap positions for a bend-over-girlfriend variation. This position may also, of course, be assumed by gay and lesbian couples or anyone of any gender identity.
