Dear ur facing difficulty bcoz of hymen it is the thin layer infront of vagina u can apply oil on ur penis for lubrication and apply little force and insert it in vaginal opening little blood will come from vagima also u will face little pain but that is normal

hello... initially female vagina is very tight. You apply coconut oil on your fingers and try to pass one finger first to feel the vaginal opening. Move the finger back and forth till it becomes loose......then pass 2 fingers into her pussy. When 2 fingers are gone inside...then place your erect penis in the fingered pussy by spying oil on your erect penis too. or contact Sexologist for further guidance.
