You are sexy not for your ability to mimic what may have worked for someone else, some other time. You are sexy for your ability to be present in your body and present in the moment, both for yourself and for me. What I like about your skin is not how it looks in a photo, but how it responds when I touch it.
You are a good lover not just because of your technical skills, but for your attitude-skills; your curiosity, creativity and compassion make you a profoundly good lover.
You are attractive not for the way you look, but for the way you look at me.
Falling in lust with someone because they fit the mainstream ideal of what is beautiful is going to fail most of the time. When the initial rush wears off - sometimes after a few months, sometimes before you even get into bed - you and your partner are left with whatever beauty you've managed to create on the inside - the rest is mostly irrelevant. Do you have what it takes to get past skin-deep beauty? Have you chosen a partner or partners with the same skills? Have you spent as much time and money improving who you are as you have spent on your wardrobe, hair and makeup?
Chasing people who fit the stereotypical mold of beauty will become tiring. You have to keep swapping to someone new every time you hit the wall of reality - or perhaps settle for a life without lust. Be more open about how you think of beauty; it is all around you. It may or may not look like what you were expecting, but it will be far more valuable to you.
Did I mention that you're really sexy?
