As my estrogen levels have risen, my sex drive has also risen. I am far more interested in sex now than I was before. However, it takes more for me to actually be in the mood. Basically, before hrt if someone mentioned sex I was good to go. But now I require that they actually make an effort to make me feel wanted. Take last night for example. I really want to have sex, but my bf just came over after work, complained about his day, and asked if we could move into the bedroom. Once he did that, my desire just disappeared.
I don't know how things are between you and your SO, but perhaps you need to try a little romance. It doesn't have to be a big gesture. Just thoughtful.
