Me nd my bf today nd most times he thinks of himself. Im starting to question our relationship nd emotions. What bout PASSIONATE SEX. Not being selfish. He only sometimes give head. Especially if he wants head from me he will go down. Im thinking its for me, but really its for him to get in return i noticed. Also i dont like when he is on top from front cus he be too high up & its hurts my back after awhile trying go along up nd dwn with him w/o being a layer than nd get sexed up not doing anything. Anyway i like it from the back but he prefers laying dwn from back than me on knees.. Than few min ago we stopped having sex (we were on our sides) because he wanted to go in a position i didnt want. I was EXTREMELY WET THIS TIME & only wanted position comfortable not a work out unenjoyabke so i can cum.. he gets mad nd SOFTENS UP!! Now we laying here not tlkn like WTF GIVE ME INSIGHT TO THIS. Im starting to be irritated!!! Fuck him nd this shit because HE DOESNT WANNA DO MY POSITION WHEN HE INTO SEX MAJORITY TIME SO NOW HE CAN BE MAD?
