I saw a tanga while a young lady lean

It wasn’t hard in the sexual way, I worked all day long and the day was to dynamic to think about it. Even I saw a nice tanga and thought a while about saying that to the young lady. I’m almost sure to shave tommorow, because it’s time for it. I woke up with an half-errection. Strange for me is that by comparing yesterdays testis picture and the one of today, my testis are smaller. But this is explainable through moving of the testis. Some times they are whole in the body, sometimes whole outside. So analysing the size (volume) of them could be harder then I thought.
