Back to the mention of HPV, it is the most common, yet strangely the STD fewest people know anything about. This is taken from healthandhpv.com:
"According to the American Journal of Medicine in 1997, 74% of sexually active people (aged 15-49) will get an HPV infection at some point in their lives. I have also heard 80% from other sources, and this could well be true because STD infection rises as time goes on. It is made up of three different kinds of people: 1. People who currently have warts or dysplasia, 2. People who have, at some point in their lives, had warts or dysplasia, and 3. People who are carriers of the virus but don't know it because they never had any symptoms. Together, they make up 80% of people having sex today."
80%!!!!!! That is scary, and the reason it's so common is you will carry it in your system and spread it long before symptoms begin to show, if they appear at all. Plus, there's no test. You only find out you have it when it's too late.
Hate to point out this scary fact, but for anyone who thinks you'd know the instant you pick up an STD... No, no, no!
By the way, as just a parting bit of info, there is no cure.
Have a nice day!
