Long term relationship & sending dirty pics/texts when we are apart?

I’ve been with my boyfriend for nearly 20 years now- we are both early 40s, WFH, no kids & what I consider an active & very kinky/experimental sex life. So given that, I thought he would be down with the idea. Instead he rejected it and said that was for when we were early in dating & should've done it then. I’ll admit I was definitely more reserved when we first dated and am WAY more sexual now…. But it just struck me as weird? Just wanted other opinions on it…
