Am i fat...............?

i'm 5'9 and i wear a size 7 pant, sometimes size 5 or size 9 but mainly size 7. i'm about 160 pounds, i don't weight my self constantly only at the doctors. the reason is i was with a guy who was muscular and we were getting physical and we were talking about something and i commented about my pudge on my tummy and he said something unconvincingly and didn't really try to deny it. i know it doesn't matter what one guys says, all guys like different things, most guys like girls my size, but you can't deny that it doesn't hit you and get under your skin a little.
