And we absolutely love having sex outside. It adds to the thrill, the excitement, it boosts the level of arousal making his cock harder. Ladies, lead your man to somewhere different. Find a secluded spot in a park and suck his cock, jerk him off while he's driving somewhere.
There's something about stroking one out with a buddy that brings a sense of belonging, commonality, feeling part of a brotherhood.
And, it'll get those full-bore boners back.
