I've been up to 2 grams a week before and never 'needed' an AI. Meaning no signs of gyno. But that doesn't mean I didn't have elevated estrogen levels. For me its a delicate balance. If i get estrogen too low, I literally cannot achieve an orgasm. I typically last a long time anyway, but my now wife and my first night was a low estrogen night. 4 hours later she tapped out, convinced I wasn't into her since I didnt/couldnt finish. Nothing could have been further from the truth. Makes for awkward situations, guys can't convincingly fake an orgasm....
