Well I am a 34 year old woman (nearly 35) and am in a relationship with a 21 year old guy. So, it's not too unusual
In general, I do look younger than my age. Most people think I'm still in my 20s even though I've got three school aged kids (before they know I've got kids they usually assume I'm in my early 20s, people who know I've got kids tend to think I'm about 28...)
I'm not exactly a hottie either
Also, I have absolutely NO idea how to tell if a man is interested! I met my boyfriend online, and he told me he was in love with me before we'd ever met!! In "real life" I wouldn't know if a guy liked me if I fell right over him!! (I was married for 11 years and with the same man 13 years before meeting my current boyfriend, and in that time I could tell you that by my observations not one single man showed me the slightest bit of interest!)
