hi mounika..<br> if u want to have sex and if u r having normal pregnancy without any risks, then u can have...its nt mandatory tht for normal delivery sex shud b done..ya its true tht hormones released during sex and hormones in semen helps for induction of labour up to some extent..so its nt mandatory..<br> sometyms it worsens the pregnancy by water breaking,membranes ll gt ruptured etc..so my advice is if u want thn oly u can have tht to in comfortable position...otherwise its nt necessary..
