about a week ago, i was at a strip club and got a 'lap dance'. although it got a little more involved. most of the time, she grinded on me, both of us had our underwear on, and she reached down inside my boxers and rubbed me with her hand. at another point she took my penis out and touched it against her underwear. her underwear stayed on the whole time and she mostly grinded on me with both of our underwear on. am i at any risk for an std? i would assume not, but i could really use some peace of mind.
