purple spots on crown of penis

[dude567]

First of all i am in the desert and have been away from my wife for about 6 months so there is no way i could have gotten this from sex. second i havent cheated on my wife so any sexual contact with someone else is totally out of the picture. about a month ago while masturbating i noticed this purple bump. the bump was right about the crown of the penis. after masturbating i examined my penis and couldnt find anything. then i got curious and examined my penis the next day and found a purple spot but it wasnt a bump it just seemed like a bruise or something under the skin. the only way i found it was becasue i knew what i was looking for otherwise you cant tell anything is there. i went to the doctor and he examined my penis but couldnt find anything that was related to an std. so now a month later, about 4 more spots have appeared. the thing is i can only find them easily when erect but when im not there not easy to find unless you know what your looking for. also while im erect it seems like all the spots bump out.  while im not erect they just look like there under the skin of the penis head like really dark purple spots. also when i squeeze my penis while erect i can notice them but i dont squeeze hard because im not gonna damage my penis. also i have not masturbated since i found the first one and there not gone. so what i would like to know is if this is penis cancer? i posted this question in dermotology and i was suggested that it coul be please help i am extremely terrified.
