non-lucid

So for the past few nights, I've been having some interesting sexual dreams. I have been very happily with my boyfriend for over 3 years, and even after a child our sex life has remained very healthy. The dreams involve men who I have been attracted to in the past, usually that I went to high school with. While I'm having these dreams, they are very vivid and very pleasurable. I wake not necessarily feeling guilty. Also, after having the dreams I feel a very strong pleasure looking back on them. I am very nervous about telling my boyfriend, really I'm not sure I even should. Could someone give me some insight as to what they mean?
