Me and my partner both are virgins. For the last two times, we tried having piv sex(penis in vagina) but we couldn't. He fingered me but when he tried inserting his penis,I couldn't get it inside. We were doing it in missionary position.No matter what he did, I couldn't get aroused and was not lubricated enough to get his penis inside. And also his penis was tilted a little bit downwards. So I just want to ask how will we be able to have piv sex and in which position should we try doing it first
