bruising on upper leg

i contracted hpv four years ago, but have only had one wart appear on my penis in the last 4 years.  I also have molluscum contagium or whatever that is called, but unlike others i have read about, mine itch is that normal.  
About a month ago though i started noticing bruises in the shape of thick lines about two to three inches long on my inner upper leg, now the bruises are starting to spread to my outer upper leg and hip.  They almost look like large bruised stretch marks. any idea what they are?

Well, it sounds like stretch marks, which often are purple or dark lavender. Doesn't sound like HPV or any other STD. But see a doctor to be sure.
