I've not had a problem with breakouts (spots?) but I have had a problem with odor. Panties breathe less than underpants. Even showering and washing thoroughly every day meant I could last about 8 hours before the odor would return. Recently I took to using a flannel which gives me 24 hours odorless, make sure you scrub vigorously all around the crotch, behind the testes and under the foreskin and dry well.
