I am a straight guy who loves sex with women. When I cannot have a woman I just Mastrubate.Here are Some great techniques I use. I love to lube my cock with baby oil and ram my penis in between the slit of a car's armrests, vinyl or leather seats to a massive orgasm.
Take a ladie's shiny black patent leather purse or hand-bag fold it into the couch cushions or matress & box springs
Lube up, insert your penis and thrust away!
A section of that Black Tubular Rubber Foam material used to insulate Refrigeration lines gives an almost real vagina feel. I cut off a section, Lube up with mild hand soap, slide my penis in and jerk to a wild orgasm.
Anthing soft, Leather, Vinyl such as Bicycle seats, Lawnmower seats, Bar-Stools are great to hump on. Lube up and tuck your penis over your balls and hump away!
