Spots down there.. what are they and why are they there?

i think they're spots anyway they havnt got like a white head on them tbh one looks like it scabbed over but theres one on the inside aswell theres 3 altoghther it isnt painfull when i go the loo but to touch they a bit tender. About two years ago i had sort of ulcers & went to walk in cenrte then GUM clinic they gave me meds it cleared up but they didnt get back to me with my tests reulsts so dont know what it was but this is different.. what is it? :S help!
