Gosh how ignorant! It absorbs beautifully vaginally, better so, in my opinion as it does not have to bypass the liver etc. Works a treat. Many ladies use it that way, I know it not officially licenced to be used that way but we even have ladies on here who use it rectally but vaginally definitely works yes.
The discharge is perfectly normal, you may see bits of the outer shell in your first wee as well. Just shove it in when you get into bed, works great.
