me and my gf hav got very physical over the past few weeks, we hav both masturbated each other and seen each other naked etc. now were both 16 and she said shes thinkin bout havin sex for the first time, now i love her and i want her to be my first because we are both virgins. she said she feels the same and wants to make it special, but the thing is, she is absolutley terifed of getin pregnant. ive told her that i will use contraception and she is on the pil, but she is still realy scared incase we hav an acident and she becomes pregnant. i dont want to force her into anyhting, but i love her and want her to be my first. what can i do/say to reasure her that she wont get pregnant?
