my name is tnk, have a question on stds. me and my husband have been married for 6 years and we recently did something very foolish and stupid . we decided to get drunk and have a threesome , needless to say we are now regretting it cause the worry of catching something is weighing in the back of our minds. im 24 my husband is 31 and our height and weight i dont figure matters , but anyways, my question is how long does it take for a std to show up ? please write me back with this regard . sincerally a very stupid descision.
