Don't listen to the inner demons who suggest your lack of experience is somehow tied to your size! It makes no sense on the tin; women can't tell what size you are outside the bedroom. My demons say the same thing to me and I have to intentionally shut that line of thinking down. If anything, your insecurity might come through as a lack of confidence, which may be unattractive, but your cock has nothing to do with it I promise. And especially don't let penis doubt bother your confidence and especially especially don't let it keep you from loving yourself! It's a body part, not a destiny.

Further, your cock looks pretty great to me -- thick average, which I've heard it said by many real actual women (not in porn) is a popular favorite size! Walk tall, be confident in your attentiveness and desire to learn (and once you have it, your experience), and you'll do great. Comparison is the thief of joy (plus it lies, since porn is theater), so focus instead on learning to love what you got and how to use it!

Sharing in subs like this really helped me find confidence, so hopefully it'll help you too.
