Ok, "Rattakorn", not to sound like a total prude, but a couple of your word choices are extremely inappropriate. Especially since this is a business correspondence and we don't know each other. I am confused as to what "vaginal secretions" have to do with preparing the soil or "cervical mucus" has to do with any of this.
Please, have someone who's fluent in English respond as your directions make absolutely no sense whatsoever.
Thank you,
Peggy Slater
