Dear Blog Reader. How do I tell him I’m no longer interested in sex?

Dear Samuel,

I met this guy through a friend. We got into the habit of chatting and we got to know each other even though we hadn’t seen physically since he stays in the United States.  

Along the line, we developed feelings for each other and after a while, he decided to come to Nigeria to visit me.

When he came, we stayed in a hotel. I was so happy because I really liked him. He also claimed to like me as well. I went through a bad breakup with my ex, and I just want to be careful.  We stayed in the hotel for three days, we made love. He came inside me, so we had to get a contraceptive. I was really scared because I didn’t want to get pregnant. I have planned my life and getting pregnant now is not in the plan. When I got home, I was scared because we still had unprotected sex. I wasn’t too sure I was safe so I got another contraceptive.
While I was at home, I gave a lot of thoughts to the disappointment my parents would feel if I should get pregnant now in addition to the turn my life would take.  So I decided to stay away from sex till I get married.

 Now I don’t know how to tell him that I have changed my mind about having sexual intercourse with him since we are now officially dating. I’m scared that he might not be interested in the relationship again as most guys love having sex. I don’t know if I should tell him or not.

 Please Sam, what do I do?
