Hey ladies.....i am almost dry down there even if i am aroused. I did almost everything i could like drinking lots of water and all...dunno what shud i do.... even during my fertile week i am not so slick. i dont want to use lube i want it naturally. i know my DH is also disappointed by this fact but he never says... btw i am 25, ttc #1 since 5 months.
