How can I address the situation where my partner has a lower libido than me and avoids physical intimacy by making jokes or turning the moment into something funny? We've been together for two years, and whenever I try to create a spark, she shifts the mood into humor or acts as though she's hard to get or control. She also never lets me know if she’s ever turned on or not, which makes it harder for me to understand her feelings. How can I communicate effectively and create a safe, comfortable space for intimacy to grow naturally between us?
