He's not well endowed.

So girls and guys obviously talk about sex and recently I've become more comfortable with disclosing my sex life with my girl friends, well I was talking to them and they were talking about the guys they sleep with have huge dicks.. I've been with the same guy 5 years and I've got nothing to complain about the sex is amazing and he's always conscious of my needs. But when my friends asked if my guy had a big dick I didn't know how to respond.. He's not a pornstar so he's not going to have a 9 inch dick. So I said he was average(5.5-7 inches, ps. We've never measured because I feel like it's degrading to him) and they kinda laughed.
I feel bad for disclosing that info now because I love him and like I mentioned before he always makes me orgasm so if it bad that he doesn't have a big dick? Did I fuck up telling them he isn't huge? Should I have just lied?
Update: you girls have made my day! Lol yeah he's the best I've ever had and I love being with him and you are right I shouldn't be bragging because next thing I know they might want what's mine.
My grandma always told me friends are only your friend until they find your BF attractive they aren't stupid.
