In response to one sexually inexperienced member's fear of trying out new positions with her boyfriend, here's a combination of inspirational thoughts and instruction from other iVillagers

There isn't a right or wrong way to have sex. There are some techniques and positions that work better than others, but the most important ingredients for good sex are relaxing and letting yourself go.

Sex can be wild and energetic, or soft and subtle - very small, slight movements can have a powerful effect. Either way, good sex is spontaneous. A lot depends on your flexibility and your imagination.

As you become more sexually experienced, you'll get to know what turns you on and off and you will feel braver experimenting with each other. But first, start with these positions.

The beginner's guide to a basic sexual repertoire

1. Some people don't find the missionary position that fulfilling, but it's basic and a good place to start. The woman lies on her back, with her legs apart, and the man lies on top of her. If you get your legs in the air that will liven things up - the rest is up to you.

2. If you fancy getting on top and he keeps slipping out, try putting a pillow underneath him. This will raise his vitals, making it easier for you to sit on his penis with your knees bent. A good technique to prevent him from flopping out is to lean forward and just move from the waist. It also gives the clitoris a workout. If you get this position right, your boobs will probably amuse him.

   A variation of this is to get him to sit on the end of the bed, sofa, wherever, and for you to sit on his lap with your legs around his waist. You may find this a bit tricky, depending on his penis size.

3. Rear entry or doggy style just has to be the best, as it allows deep penetration. With training he can hit the sensitive spots and fiddle with all your bits with his hands.

4. If you're feeling adventurous, try out the back-to-front position. He lies on his back and you sit on his penis facing towards his feet. Your legs should be bent back so that your soles touch his thighs. Lean back, putting your arms behind you to support your weight, and move from the waist. This position is brilliant for tummy toning. His hands are free to wander, and you can get spectacular results with perseverance and practice. If he keeps popping out, move down towards his feet and sit upright.

5. No doubt you will discover loads more positions once you've had a bash at these ones. Spoons, sideways, face-to-face and up against the wall are all goodies.
