Neither, I was just asking. I've never been in a situation to have sex while menstuating. I was on depo (short term for a birth control) and it allows me not to have my period as long as i am on it and i've been on it for a year until I recently stopped.
I've never heard that the blood dries up and blocks the front door. Even when i'm not horny I am still wet somewhat. That's something new.
Remarks like those are what make people suspicious that you're not who you claim to be.
Depo Provera has a host of health risks associated with it. Depo causes reduced bone density which can increase your chance of osteoporosis when you're older. This change is irreversible and going off Depo won't undo any reduction it did. Because of this same issue, it won't typically be proscribed to young women, because their bones are still growing.
If you are 19, as you say, it's unlikely that any doctor would have ever allowed you a prescription for it, and it's only available via prescription.
Also, your periods don't generally go away immediately when using depo. It usually takes about a year of using the drug before you stop having them.
And it should be obvious to anyone with a clue that Scaredlittleboy was being sarcastic, but you took him seriously.
All those kinds of things, taken as a whole, give the impression that you have no real experience with the subjects you're speaking about. That leads to two likely scenarios...
1) You're under 18
or
2) You're not a woman
I'm not gonna get all over your case for it, because I don't actually care and the more threads around here the better, but I wanted to help you understand why people are doubting your identity.
