Do some people contract STDs more easily than others? I have had about 20 sexual encounters (different women) over the past 20 years, and I have (stupidly) not used protection in about half of those encounters. Some encounters were with escorts as well. I have never tested positive for anything. I have been tested as recently as 6 months ago with a full panel from simple chlamydia thru HIV. All negative.
I am not seeking to get an STD, I just wonder, frankly, why I have not run into one yet after some very stupid nights. There were a couple of times I fully expected to be positive for at least chlamydia.
I would like to hear some feedback on this one. I am a white male of northern european descent and I am circumcised. 100% of my encounters have been in USA or northern Europe. These are factors that could matter as well.
