hello, i am 18, M and my partner is 19 F. both of us are first timers and it's only our third time doing it raw. usually, every time we do sex, it always hurts the first time i put it in but she says the pain usually goes away after some motion. It also hurts her vulva(?) or her outside vagina skin after. I did some googling and lack of lubricant is one of the reasons that appear but i want to make sure, and what can i do to help her?
Another thing, is there a possibility that she gets pregnant even though i haven't finished once in our three times of doing it? i didn't do the pullout method, just some movement back and fourth and never really got near the feeling of "finishing." I haven't bought a condom due to lack of money and i barely get allowance since school's about to end.
TYIA.
