Sex is a no no for me

Ive dated a lesbian before i had a guy. Weve dated for like a year until i have to go here in illinois. Then we broke up. After 2 years, i met this guy. His presence is the same with my ex. So i tried dating him but im not that serious because i felt like hes gonna left me and do what my ex did to me. He's the first guy i kissed and it was the best. Thats when i started to like to see him everyday. He turns me on. But i hated it when he wanted to have sex with me. He forced me when i dont want it. While doing the intercourse i dont have any reaction at all. All i wanted to do was cuddle with him. But i dont think thats enough for him. Weve been dating for a year and 4 months. But i dont think i loved him. And when i refused to do it with him. Thats when he started to change like calling me slut or everything. Then we broke up. Now i feel like theres not love anymore but just  sex. Thats why im afraid to date someone.
