Cupcake... start your own thread for your own problem... everyones situation isn't the same.

Question moved from piggyback.

Now this has its own thread... How old is he? Is he on any medications? Does he have any medical Conditions... and last... has he been to see a Doctor yet?

What has he said about the problem?

Has this been a problem for a while or just the past week?

Has he been distracted or preoccupied with anything like school, work, family, friends, etc.

The more detail you can give , the more accurate
The answers or suggestions will be.
Pay close attention to anything that may be
Different or changed since the issue began.

Should have caught this before... but how old are you?

I think it's important to not jump to the conclusion that he's not attracted to you anymore. There could be many explanations, and that is most likely just going to make matters worse.
