I've been dating someone for over 2 months, first he said he just wanted sex then he said he realized that I was really special and a hard to find woman. Now he wants to cuddle, kiss and spend lots of time together, he calls a lot and is introducing me to his family and friends. He looks at me like he wants me, and like he is in love. We are going on vacation together. He is very respectful. But now he's not wanting to have sex. He has a lot of things on his mind right now that are distracting him I know. What's up with that?
