I'm married and I hookup with a lot of strangers
That is very problematic. Why do you act this way and being disloyal?
I feel incredible remorse and shame and I wish I didn't have to do this.
I'm glad you feel such remorse, so isn't it a good idea to stop and finally come clean? Your partner needs to know of your misdeeds in order to save your marriage, and take lots of STD tests because you don't wan't to spread it around.
It's my wife's fault for not wanting sex.
If your wife doesn't meet your needs  sexually, then what you can do is tell her and see how you can resolve that issue. You're actively cheating on her and it doesn't justify your actions as you're actively causing harm to her. You can divorce her if needed so that she can find someone else that will be loyal to her, and you can find someone else that can satisfy you sexually without cheating.
