So I have know my boyfriend since we were in kindergarten and were in 8th grade now almost in high school, and we just started dating a week ago. I really like him and he likes me to but all he wants to do is have sex. I don’t think I’m ready for that but idk how to tell him, and I’m afraid that if I do he will break up with me. Idk what to do please help me!
