Really these are SO many threads about shaving...chill, put some baby powder on it and leave it alone. wear loose fitting underwear and stick to cotton fabrics.

Keep the crotch cool and the irritation goes away real fast.

Shave bald if YOU want to, what others think makes no difference, they're your hairs do with them what you wish, as people have mentioned here tho, the more you shave over time, the less the rash develops.

Next time use the searchbox above a read the threads devoted to shaving, there must be loads.
