Watch: Man left with an erection while standing behind a bikini clad woman

A man was unable to control himself while standing behind a bikini-clad woman. This caused him to have an erection and it was caught on video.

In the video, a number of men and women in their swimwear can be seen standing on a queue close to a pool. Behind one of the women stood a man. Soon, the woman began rocking her body and the man behind her had an erection that stood and rubbed against the woman's butt. The woman immediately stopped rocking her body when she felt him against her bum.
