The Missionary Position

Laying flat on your back won’t give your man the message he needs or give you the climax you desire. Remember that an orgasm will be more achievable if the clitoral area is massaged in motion. Tilting your pelvis slightly & thrusting your hips with his will allow maximum stimulation to your clitoral area. Either wrap your legs firmly around him with your ankles crossed whilst grinding in unison or anchor your feet firmly to the bed & use your legs with abdominals to thrust for heightened arousal for you both.
The use of a cock ring is most effective whilst in the missionary position & the extra hard simultaneous thrusting will deliver maximum vibrations to the clitoris with a pelvic tilt that encourages the onset of orgasm (not to mention a rock hard penis for your man).

In the same way you don’t want to lie motionless, use your hands to enhance the missionary position’s sexual appeal. Grabbing your mans bum cheeks or scratching his back have real sensory appeal. Why not have a go at playing with his anus a popular erogenous zone, lots of men enjoy having their bums played with & a lubricated finger is the best place is start. Simply apply pressure to the opening of his anal passage or insert your finger a little way. For the more adventurous try a prostate toy whereby you can maintain the missionary position & shift your upper body to the side enabling you to massage his prostate whilst the two of you are in motion.
If your partner lifts his upper body onto his arms you can also put those hands to work with a clitoral massager a sure fire way of achieving orgasm during penetration.

The missionary technique can also contain some variety. Try lifting your legs straight in the air whilst your partner holds your ankles to thrust or move your legs further back towards your head which will intensify penetration & make your man feel much bigger in the penis department (this works great for after childbirth when some tightness may be lost).
Another method is to clamp your partner once inside you by closing your legs with his legs on the outside. This also makes for a tighter fit & the pressure of your thighs when you squeeze will maximise the friction for your clitoris. This position can also be effective for multiple orgasm as squeezing your legs together whilst pulling your pelvis upwards after climax can induce a second orgasm.

The missionary position can also be great for other erogenous zones. Anal sex can be easily mastered in the missionary & tends to put less pressure on the back passage. The G-spot can also be easily reached either by placing a couple of pillows underneath your bum to reach the correct angle or by adopting the legs to the head position which pushes the penis to the g-spot area for a pleasurable massage with each thrust.
