So I am 18 male, and I’m in my final year of high school. For the past year, my twin brother and I (identical) have been taking showers together. For context our shower is really big, it was designed for people with disabilities and the shower head is long (not good for saving water). So we’re far enough apart that we have a good amount of personal space. It started when we were in a hurry to get ready for school one morning (I think I had a math test that day). He was in the shower, so I asked if I could get in and he agreed. We would pretty regularly be in a rush for school and one of us would have to wait for the other to get out of the shower so after this it kind of happened a lot and became a regular occurrence. Even when we’re not in a rush, if one of us needs to shower and the other one is already in there then it’s more convenient if you just get in.
Honestly, it’s really nice to have a place where we can catch up and chat. He asked me whether showering together made me feel uncomfortable. I said that he didn’t, he said it doesn’t make him uncomfortable either. Of course, I love my twin brother but not in a romantic way. Neither of us have any romantic feelings or desires toward one another. I haven’t seen him hard and nor has he seen me hard. Honestly, it’s like showering next to a mirror. Our bodies look the same (and yes down there looks the same as well). Our parents know and they don’t mind. I’ve told two of my close friends about it and they said it was definitely unusual, but didn’t think there was anything inherently wrong with it. I think I agree with them, but are they and I right? Is it wrong? I am fully aware that it’s unusual.
