1. I told you before.. we have 3 holes XD The first hole (under the clitoris) is the peehole.. it's not very noticeable but you can see that it's a hole~
2. The tampons are for the second hole (vagina).. You just put them in, wait a few hours, put them out again
It's not very difficult XD
But I prefer sanitary napkins
3. Menstrual happens through the second hole (vagina).. that's why you put the tampons in there XD
What exactly is your question about the menstrual?
