I and boyfriend are in long distance relationship. We meet after 3-4 months and when we meet we stay together for week and have sex many times in a day (4-5 times). But the intercourse doesn't last longer than 20secs. What can we do to have longer intercourse. And we like having unprotected sex does that cause any harm. He removes his penis before the sperm comes out. And he prssess my breasts vry hardly and also bites till skin is red to arouse me does that have any effect on the size of my breast. Are there any positions where we can have unprotected sex and not even get pregnant. And I have gained allot of weight since we started making out is sex and weight related.
