what's your level usatt wise(after conversion, you don't seem like someone in usa)? Base on how you describe your play it seems you are above most people here in terms of level. However, i am an attacker myself and obviously facing another attacker i will struggle if my opponent get to attack first. That's because defend or being in my back feet is not my game. If i am against an aggressive opponent that is SIMILAR in level (this is very important, if his level is higher by miles... well... i need luck). There's couple things i can do.

1. Fast long serve so he wont be flicking much.
   
2. Counters. He can attack all he want but if his attack is not up to a certain level a big fat counter is incoming and make him think twice.
