me and my partner have together for eight years and have always had a brilliant relationship and a good sex life. we now have 2 daughters age 23 months and 8 months.since the birth of my second daughter i just havent felt like having sex at all with my partner.and when i do i dont enjoy it and usual fake it. i feel i am only doing it because i have to to keep him happy and i try and avoid it if i can. i dont know what it is . i blame it on being tired from looking after the kids all day but im not sure that is what it is. i dont even feel turned on by him anymore and i dont like him touching me. i know it sounds awful and i feel awful . i love him to bits and i dont want to feel like this.its really getting to me. i cant talk to him about how i feel im too ashamed. we're supposed to be getting married next year. what can i do ? xx
