The first time is a little painful. Especially if you’re not ready. I am not saying you should have sex, but there are ways to make it more comfortable even enjoyable for you. Relax and use plenty of lubrication (if not it will not go in the first time), plenty of foreplay to make your body more accommodating.
Don’t expect too much from the first time. It is usually pretty uncomfortable.
But, don’t rush yourself to have sex. The hymen IS the painful part…it is the film that is ruptured for the first time that bleeds a little but once it is out of the way, then the pain should subside immediately…
sometimes that hymen is extremely frustrating in that it is a bit flexible and may or may not bleed the first time…so then..UNTIL it breaks it will be a tad painful…but remember that the guy DOES NOT want to hurt you..so he can be reluctant to break through…he doesn’t want you to cry and yet..it is kind of “a rock and a soft place” (sorry nothing “hard” about a vagina-except breaking the hymen 
I am led to believe that the more you relax and let the situation take care of itself..the less it will hurt…
