Why do i always break out in-between my legs? i don't sweat a lot. but always have a bunch of pimples and some blackheads. what can i do to prevent?

It depends,,,: It depends on your body and possibly your habits. If you're heavy your legs might rub together and get irritated, causing pimples, etc.. If you wear tight clothing, this can happen, also if you don't dry yourself there after washing. So if these need to be corrected, this can be helped. If they don't, then antiseptic or drying creams might help. If it still persists, see a skin doctor.
