DP and I have been together for almost 17 years now. 2 out of the last 3 times we’ve gone to have sex he’s had trouble getting hard. It’s never been an issue the whole time we’ve been together. My libido is often low due to a medical condition so you can imagine how disappointing it is for both of us when we are both in the mood. He’s always been horny literally every night. What c@n cause this type of issue. He says he really in the mood but can only get a soft erection.
