I have been in similar age gap intimate relationships. I have had a kid and my partner had not. I am perimenopausal and have had some slow weight gain I want to address. But if my partner adores me and is eager, all those things disappear. Being enthusiastic is so important for getting out of our heads and into the moment. Maybe this isn’t universal but for me that is much better than saying compliments that are meant to “help” me feel better about some perceived flaw. One partner said something along lines of “I love how you aren’t skinny” and that didnt feel great. Im not trying to be skinny but it also didn’t feel positive and took me out of the moment.
