My boyfriend and I have recently been getting very rough with at least 2 or 3 rounds every time. When he "eats me out" he likes to suck on my clit which is fine but it starts to hurt pretty badly after the 2nd round which causes me to not be in the mood for any more sex even though he is ready to go. My dilema is this ... today he "ate me out" for a total of probably an hour which included him going down, 69ing, and him having me sit on his face. After a while my clit was swollen [not from being aroused] and it hurt for me to even think about him going for it again. Also since I'm in pain, my vagina is basically completely dry yet he still wants to keep going. How do I tell him that it's not comfortable for me when he sucks on me and it causes me pain?
