Yes, you are! If that’s the longest you’ve done then that’s brilliant. I’m proud of you. I know you read on here about people going for much longer but different strokes for different folks and you need to find what works best for you.
Make sure you’re edging as well as not cumming, and by day three (if not already) hopefully you’ll start to feel the ‘denial high’ that makes you feel happy and horny and full of energy.
Once you get used to feeling like that it makes denial easier, and well you’re basically an addict for life. Welcome to the party, you’re so fucked.
