This sounds perverted but...
The thing I miss most about my ex is her boobs. I mean they were big, soft and awesome. I'm sure all males will appreciate that a nice pair of boobs is brilliant. Of course its not the only thing I loved about her but they were the first thing that attracted me to her a year and a half ago and I had a lot of fun with them. Since I'm getting over her emotionally they are something I still miss. Is there anything wrong with that? IIN?
