Hello >WAVE<. how's Life down under: however ..........
Yes the vagina can become dry so that it doesn't absorb sufficiently. Some ladies need two doses occasionally, did U try that yet. 10mg is such a small amount so doubling up might give the area a 'boost'.
Also take pain relief to ease that 'need 2 P' feeling. 'nurofen' works for me, 2 pills 3 times a day.
