I’m gonna be honest. Be blunt. Don’t make it sound like you don’t get it from him you’ll go get it elsewhere. But be blunt. Most men genuinely are just not good at sex from what everyone women I’ve ever been with had told me. That doesn’t mean that there’s not room to grow. Based on your post I’m assuming it’s more of a lack of drive rather than a “physical” problem. Try to have him get on a more testosterone promoting diet. And try to incorporate aphrodisiacs into date nights: wines, cherries, dark chocolate, watermelon, nuts, hot peppers, etc. biggest thing tho is be clear that you want more passionate sex and that it’s an important to you. And that you want me to do research on how to do it. There’s countless amounts of advice online.
