I love showing my bum
Ever since puberty at 13 I have loved to show my bum. When in the showers at school, several boys said how much they liked my big, round bum. I was flattered. We had some pleasurable moments, mostly at home, or in summer, outdoors. This was my introduction to the pleasures of my bum hole as an erotic area.
At college, one of my friends was a keen rugby player and was interested in body building. Although I was not as fit as him, surprisingly, he admired mine. I wouldn't have thought that 5 feet 7 inches, 145lbs, 37-33-39 and 6 inches matches a body builder but he liked it. He would remark how my sturdy thighs compared favourably with those of his rugby friends. He asked me to go swimming with him each week. It was great fun, especially in the showers and men's room afterwards.
Fondling my cheeks and hole have both been important preliminary parts of masturbation. I have often used mirrors to look at my shaven crevice and hole and to watch my cheeks as I work on my testicles and penis - narcissistic but arousing.
In the locker room at swimming pools, I have taken any opportunities to bend over, legs wide apart to show to anyone whose body language showed interest, often as a preliminary to masturbation.
For many years I worked occasionally as a nude model for art classes. I found it very arousing to show my cheeks as well as the even more intimate parts of my body usually hidden between them. Some of the poses I used were yoga positions. Many poses expose very clearly those parts of the body usually hidden from view even when we are naked - our bum crevices and holes. These are some of my favourites:
* lying on your back, put the soles of your feet together and bring them towards your chest. Arms inside your legs, bring your hands round to clasp them in front of your feet. This is a common yoga position. Alternatively the feet can be brought together behind your head, leaving your arms free. A variation is to keep the legs and cheeks wide apart by holding the inside of each knee with the inside of each elbow. All of these positions strengthen the thighs and open the cheeks and crevice.
* Another position is simply kneeling on all fours, legs wide apart, stretching the torso up and own, like a cat when stretching itself.
* If an armchair is available, this can be used to stretch the thigh muscles very pleasurably in an easy position which can be held for a long time: in the reverse of the normal direction of sitting, rest each thigh on one arm of the chair, with your chest and arms resting on the back of the chair. This stretches your thighs and opens your cheeks to great effect.
I love to show too. One of my pleasures is going for a bike ride on a sunny day just a pair of short Lycra shorts and shoes. After a while I roll up the waistband to make my shorts tiny and expose my butt cheeks. It feels great and is so exciting when I get to a busy spot.
