It gets better the longer you stay away from it, really.
Those thoughts in early days are very insistent, but they're just thoughts. Like dwtbd said, thoughts can't make you do anything.
Mesa Man also used to say something like, "I had a thought of sleeping with that pretty 20 year old too - I have thoughts about picking up my friend's wallet. I don't do those things either. I don't cheat on my wife, and I don't steal." [paraphrasing here]
Make it something like that, something you just won't do. No matter what. This will pass.
