Umm, i think sex and lovemaking are totally different. I've had sex with a guy i didnt love. That doesnt mean we arent incredibly close, but i am not in love with him. And then there was my at-the-time boyfriend, and we were completely wrapped up in eachother, and totally in love. The way i felt for him was different. I think both sex and lovemaking are quite amazing... and each leaves you with a different feeling. That doesnt mean one is better than the other though.
You're doing something wrong. Hah, just kidding, you're young, it'll get a lot better. Anything in life besides sex is filler. Unless you save a truckload of orphans from going over a bridge, sex is the most important thing a person will do.
