No, average doesn't do anything for me. I recently had sex with a 5 incher. I gave him oral and I could put the entire thing in my mouth from tip to base and it didn't even begin to choke me. And sex was no better. I just pretended to feel it but couldn't wait to leave. I get more from a tampon. From now on if I notice it is small then I am making my excuses and leaving.
That's my honest opinion. I don't expect any guys on here to get nasty at me since I know they all have huge cocks. And yes, I know it's not all about size but it does matter as muxh as longevity.
