update
I have since found out that prostatitis sometimes being caused by untreated gonnorhea or chlamydia is still theoretical and has not yet been proven, although a lot of web sites bluntly put those 2 stds as a possible cause...
I also learned through a lot of web searching (hours and hours...) that acquiring chlamydia and gonnorhea through is also unproven and has never been documented, although theoretically possible... So, as it stands today, i dont believe I got it through , but more probably through regular alcohol consumption (I love beer, have been drinking it since I was 16, and alcohol is a known prostatic irritant!). So the bad news is I am going to lay off the beer for a while, the good news is I can continue with the s! (to tell you the truth, I dont which one of the two would be harder to give up!)
