I have recently started being intimate with a guy I have been dating. He is 10 years younger than I. While he was inside of me, he asked me to put my finger inside of me. Then asked me to put another, then said, now put all 4.... first of all, this seemed to cause dryness...and I felt stretched beyond measure.. secondly, it didn't really feel all that great for me, there was very little room.. what is this doing for him? anyway to avoid the drying out?
