Hi-ya

I am MaKenzie, I am 16 years old, and I have a boyfriend that wants to have sex, but I am not wanting too because I already have an amazing one year old boy! We have only been together a few months.... He makes sexual comments and it makes me feel uncomfortable, and I was wondering what I should do.... Any advice? I love my son and all, but I am just not ready for another! I don't want the same thing to happen again😞
