My vagina is dry and red.. it's occasionally a little itchy but maybe that's because it's dry.. no clumpy discharge... what do i do??

Vaginal dryness: You could try a vaginal moisturiser such as: Replens, Moist Again, Vagisil, K-Y Silk-E. Most are used 3x/wk until symptoms resolve. You could use a lubricant like Astroglide or KY Jelly with intercourse. Avoid any Feminine Washes or douches. If no better, see a doctor to make sure it isn't something else that needs to be treated (like an STD or bacterial vaginosis).

Irritation: Use neutral soap when you take shower , avoid too hot showers. Use cotton underwear and avoid tight pants. Use water based lubricants as needed. If it persist see a dermatologist to get a cream with some antiinflammatory ingredient such as steroids in it.
