Bunps on the inside of my foreskin

I’ve always noticed them there but I never really looked at them well, now that I looked at them well it’s scaring me I have no idea what they are. I am not a virgin a have had unprotected sex(last time I had sex was 4 years ago I’m not sure if this is relevant information) can someone identify these bumps? I don’t know if they’re forcyde spots 

Hi Tony, Sorry to do that we really do need a picture, so just above this reply box your see to the right 4 small boxes just click on the last one and load from there, from a laptop or a PC only.

OK Mate.
