My bf and I have been tg for almost five years. For the first three years we had sex a lot. This past year we don’t as much which is normal for it to reduce. But we r on a trip right now and yesterday I had my bikini on and he barely reacted or touched me when ik that would’ve made him go crazy in the past. We also showered together and he didn’t really care about seeing my body. I feel like he’s just so used to it now that it’s not a big deal or sexy anymore. We only had sex one time this trip and that was when we were high. We usually do it when we’re high. Is this normal with long term relationships?
