I wanted to reply to this thread because of my personal experience. My wife and I are new to the LS, and we're trying this to not only to start finding new ways to enjoy ourselves, but for me to gain confidence.
Prior to my wife, I've had about 75% of my exes tell me I wasn't big enough for them. It's a very difficult and heartbreaking thing to hear. I've been carrying that with me, even into my marriage. And even before I got married, I happened to overhear my now wife tell one of her good gay friends how much she enjoyed bigger cocks.
My wife has been trying to tell me my size is decent. I'm about 4"-4.5" but in the back of my mind I have this fear that she's just saying that to try and make me feel better. But it's extremely difficult to get it out of my mind.
We're hoping that trying something will help me build confidence. After reading that most guys aren't that much bigger than me kinda eases my mind but it'll take a while.
Thanks for allowing me to tell my story. I hope I can start enjoying myself sexually. I know my wife needs it.
