I’ve had sex probably about 15-20 times with my GF now and it works well in a lazy doggy position from behind, but the problems started when she wanted to try missionary. I’m really not sure how to do it – I tried it lying down and with pillow underneath her but it was just too low for me to get in. Obviously this was a bit embarrassing and we had to switch back to lazy doggy – any tips on how to actually do missionary properly?
