THESE are raised lesions so they are papules, because they are pinkish I think they are not rough- they are unlikely to be HPV
related lesions which are typically verrucous- dry scaly rough surfaced papules. But they may be result of some other viral infection, allergy
to some local medicine, powder, new under garments, because it's itchy it may be miliaria
and also a possibility of scabies
Anyway improve local hygiene, ensure ample dryness at local area, wear cotton under garments and ask your sex partener about any such lesions.
And consult a dermatologist/Physician.
Get well soon
