My penis is relatively small. It is 4.25 inches. It's not a micro-penis but, it is certainly a good 20%+ below average.

Recently I started day gaming and getting a moderate amount of success. Now that I'm actually having sex with girls, I'm worrying a lot about whether I can pleasure girls with my dick.

A lot of the advice on here is - "fuck her good". However I feel like I can never fuck a girl good, because I feel like my dick is simply just too small to be able to effectively pleasure a girl through penetration.

These feelings are very negative giving me quite a bit of sexual anxiety. The last girl I brought home, I couldn't get it up due to anxiety!

I keep thinking this girl probably has been with a guy with a 6" or 7" dick and she simply won't enjoy sex with me.

I can deal with having a small dick, but the psychological effects it's having on me is very bad. How should I deal with the negative thoughts I have about my small member?
