For me it was something that came and went. I have always loved sex though so it wasn't really worse during sex than other times. In fact I would like to have my partner tell me whatever would get me turned on the most and he would do just that right in the middle, which made it perfect for me. Sitting there and thinking through every aspect of your real sex life isn't going to get you off unless it's perfect, which isn't the reality for 99% of us.
Things that helped me:
pumping (bigger size and better sensation)
using strokers/sex dolls (to feel the proper sensations and role I enjoy)
my partner learning to give good blowjobs and handjobs
Now at 1.5 inches you should have no issue getting good sensation and I'm still growing (started topical DHT over 2 years ago, been on T over a year, pump occasionally).
One thing that might help is seeing your package from other angles. Every guy thinks his penis looks kinda small from his view but properly placed camera or mirror can show it from your partner's view and you realize that it's pretty darn big once the changes start! That was the case for me
