From what you describe, red freckles, and taking into account the fact that you're not sexually active - I think it highly unlikely that there is anything serious to worry about.
Of course it would be foolish to ignore any change in your body and the very best thing to do it to go and see your doctor.
He will give you a good examination - and remember no need to be emabarrassed - doctors are looking at peoples' bits and pieces all the time!
They could be Fordyce Spots which are so very common that they occurs in almost 95% of the population! (I think they mean the male population!) Or the other thing they could be are Lichen NItius - which are a bit more uncommon but still harmless and don't need treatment.
This is a good site which will give you lots of information about spots and bumps!. There are pictures too so you can compare what you have with what you see!
I must say I was amazed at the list of diseases and conditions which men can get!
Good luck and go check it out with the doc!
