How to tell my bf

Hi ladies I just started a relationship with my bf, we’ve been together 4 months and I am not please in bed. I’ve tried talking to him about this but not fully saying I’m not happy with our sex life. Nothing has changed.

We rarely have sex and if this is just the beginning of our relationship that scares me for when we’re further in. And when we do have sex there’s no foreplay or anything (I’ve expressed this to him how I enjoy foreplay) nothing has changed. I’m so scared to be blunt with him, what do you ladies think?
