i can offer you some advice if youre worried about your body on camera, or nervous about being photographed. as i never use models because i prefer the real emotion, its important to help the subject with nerves. (this is from a purely artistic point of view, rather than glamour type shots so i apologise if its not what youre looking for).
general rule: relaxed first, sexy second
the key is to feel sexy and relaxed at the same time. wearing something simple which allows to be relaxed is more important than dressing to turn someone else on. for example a silk night dress and stockings, even just a bed sheet wrapped around (or nothing at all) rather than dressing as a pole dancer. the erotic and sexy feel of the image comes from the subject, not just what they wear or how they pose.
eroticism as state of mind is also key. if with a partner, a massage and sensual atmosphere helps to create this while helping the relaxation. note that physical relaxation is needed not just emotional. that half asleep, sexy feeling that comes from this helps no end. a bath beforehand or candle or soft lighting are great too. whatever helps you feel sexy
inside is the aim. emotion comes across in the picture.
another tip is for the photographer to be non-intrusive, as if hes not in the room, e.g. youre left relaxed to caress or slowly undress and have your partner take random shots, or stay out of your 'personal space', even moving around to get different types of shot. keeping in the shadows so to speak (not in a creepy way of course!) or even sitting there whilst you move around the room. when someone keeps looking at smiling at the camera it can destroy the mood in a second!
i find this helpful as it allows the subject to feel less 'on show', so they can be themselves more. for the artist (or photographer) to create mood is doing their craft a great service. it helps both artist and subject, reversing the expected roles, so that the subject is more in control, and the photographer follows their lead. these are just a couple of many tips which can help you.
as i said, this is from my point of view as one who draws and paints nudes and eroticism. i dont like to use models, preferring that sexiness that is genuine rather than posed. in the end you can tell. the key to it is to get that genuine sexy feel from the subject, rather than making them feel like theyre an exhibit (or worse get nervous right as you press the shutter button and pull a stupid face

).
of course its always good (and fun) to just play around and see how you feel.
these are techniques i use and know work and can give excellent results.
good luck
