Dyspareunia: Dyspareunia is medical term for painful sexual intercourse. There are many reasons for this condition so we need to address cause. Check out http://www.mayoclinic.org/diseases-conditions/painful-intercourse/basics/definition/con-20033293. If it's lack of lubrication, there are many water-based options available. But these won't be helpful if there are religious and/or cultural reasons behind pain.
