We used to make out 24/7 & were talking about sex, now he won't even make out with me.. what the hell? I know it's not my physical appearance or my breath or anything with me, something's up with him.. help please?

Maybe he's gay.

Or seeing someone else

Maybe he is maturing faster than you are... mature people have lives outside of sex and making out... and too much of anything is going to make someone tired of it... fast.

How old are you 15 or 16? Clearly not 35 or 45 or more. Age matters... even guys can see this by the age of 24 or 25. And women grasp it years earlier.

Ever eat way too much of your favorite food before? Same thing... too much of anything isn't good. How long did you know him? I bet its not long... stuff like that never lasts long in any relationship.

I agree completely with smoothy. I think perhaps you need to ask your boyfriend these questions though. It sounds like he's either going through a rough time or is as smoothy said just growing out of the 'making out' stage in your relationship.

If he's not kissing or acting loving towards you all together, then perhaps he's just moved on from the relationship and doesn't know how to tell you.

Good luck!
