Almost 3 years ago I was in your situation. I am 19 now, I was 16 then. Dating my first boyfriend, a guy I'd grown up with and loved for forever. Sadly though, he only wanted to sleep with me. He kept talking about it, pressuring me, getting more touchy ect., even though I'd told him over and over and over again that sex wasn't an option until marriage. Finally, I just got tired of him pressuring me, and I was afraid that I'd lose him otherwise. So I did the unthinkable...
Almost 3 years later, I am a single mom with a 2 year old little boy at 19 years old.
I wouldn't trade my son for the world! He is what God used to open my eyes to where I was headed. I love my son more than anything (other than God), but I DO NOT recommend the path I chose for anyone else. It's hard for the baby that's brought into the world, and it's hard on the teenager and the family of the teen.
If you sleep with this guy, you may or may not get pregnant, but I can guarantee one thing... Waiting for your marriage bed and The One that God has for you is worth it!!! You may say, "How do you know it's worth it? You didn't wait." I know because, sleeping with someone before marriage is SO NOT WORTH IT!
You know the right thing to do. If you thought that sleeping with this guy was a good choice, then you wouldn't have asked anyone's opinion... you would've already done it.
Hope this helps. I'll be praying for you!
