It could be from shaving, try not shaving for a while and see if that helps instead use a shaving alternative like Nair hair removal lotion down there. but to be on the safest side I suggest you got to your nearest health clinic and get checked for stds. Because you never know who is having sex with who and who has an std. So better safe than sorry.
They could be ingrown hairs. I shave frequently also and I tend to get them every now and then. They look exactly like you are describing. Most of the time they go away on their own, but if it stays red and begins to hurt all you have to do is pop it and pull out the hair.
yeah, i totally get these as well - they are definitely from shaving and/or ingrown hairs.
It does sound like razor bumps/ingrown hairs. I wouldn't pop them, try applying heat packs to the area. Exfoliating regularly will help prevent/reduce the ingrown hairs.
