Yes. I totally had the manliest straight buddy in college. He was somewhat petite but fucking great body. I had never seen him change and always avoided it so I wouldn't put him in the position of feeling uncomfortable with me. We ended up very close and when I did see him naked I just told him..."You have the biggest fucking dick." I just blurted it out. He was comfortable and liked the comment. He was never shy after that. He liked the attention and we really loved each other on so many levels. We each have someone in our lives now but still try to get together, as couples, a few times a year.
