Sex Question

[roboflop]

The other night I had a drunken one night stand with a chick from the bar. Was so drunk that in the heat of the moment I didn't use protection. I know, what a stupid thing to do. Anyways the next day after work I came home and took a leak and noticed a little bit of crust on the hole of my dick. Has anyone ever experienced something of the same. Note I have had this happen like a year ago and nothing ever came of it. I have been tested since. Is this buildup normal when getting some from a new chick or what?
