AG-Guys Cialis--man's best friend!!! (second to my golden retriever of course). That shit has me rock-hard for days and it increases my sensitivity too.
Sounds like your estrogen levels are too high. Once you get the AIFM in your system you'll be okay. I had the same surge in bonors for the first few weeks of Test-E and then the dropoff just like you. Once I got AIFM (around week 4) it was ON like DONKEY KONG for the rest of the cycle.
About your self-confidence issues: if you're doing AS in the first place, you're probably into your body. If you're into your body, it means you probably look better than 95% of your competition body-wise. Most girls love dudes with nice bodies. She was one of them and she wanted your dick because YOU DA MAN NOW DOGG! TEST E ROCKS! Now go try and fuck her again before she finds some other meathead who will.
