I'm inexperienced and in my mid 20s and my partner is in their 60s and has been having gay sex since they were a teenager We only do side stuff do to his ED but I feel like he is bored and I want to wear things or try new things or do something to keep him intrigued and excited about sex. However, whenever I ask about things they like or think are hot or even if I try doing things I observed they Woof at in media or the street they are not super interested in it. They say they are kind of over all of the kink stuff, clothing, lingerie or whatever.
