Sir/madam during intercourse my wife feels pain but when doing intercourse after couple of days then for the first time she feels ok but then if I wil do the same for second time she feels pain. When we stopped intercourse for couple of days she herself regains normality but problem exists only when we go for intercourse for second or third time in a row. We consulted doctor and she recommend. Potrate-MB6 &Monoxef-O 200. But nothing happens so please suggest best.
