Tight Fit - If you want to try experimenting with different sexual stimulation, you can increase friction by the woman keeping her legs together during penetration. This works with missionary and also doggy-style. What you will both feel is that penetration is tighter and some women very much enjoy the self-imposed feeling of restriction when their legs are together. Hint: close your legs after initial penetration or this will be much harder work!
Vibe it up - if you would like to experience more of a sense of fullness during penetration, then use a slimline vibrator alongside your partner's penis. Although a smaller penis can stimulate the sensitive entrance area of the vagina, some people do like a feeling of fullness during sex and this is an easy way to achieve this. I'm not talking about an enormous life-sized dildo, but a very slim pocket-sized vibrator - probably no bigger than a finger. I think your partner needs to be feeling pretty confident before you approach him about this, so use your judgement. It will also stimulate his penis so he has everything to gain and very little to lose.
Carry-along - if you are your partner like a little outdoor fun, I suggest one of you takes along your favourite sex toys to surprise your partner. Using a toy that you may usually confine to the bedroom in a totally different situation heightens sexual excitement enormously. At a party, at a picnic, - I am sure you can conjure up a scenario that works for you. This appeals to people who like to take risks -but maybe don't take stupid ones? It's your choice.
Bum Fun - if you are a woman who wants to try anal sex, this is for you. Many women say that the best position, especially for nervous first-timers, is with the woman on top. She maintains the control and can choose the depth to which she allows penetration. It makes it easier to jiggle around, get used to the feeling and resist deep penetration if you find you don't want it. Also you get to move your clitoris against his pubic bone for added stimulation.
Condom Lube - squirting a small amount of lubricant into the tip of a condom will feel more pleasurable for a man. Always useful to know, especially if you meet someone who is reluctant to use protection.
Mouth and Nose - when giving oral sex to a woman, alternate using your tongue and your nose against her clitoris. Yes, really. Because she will feel more pressure from it and you will be able to carry on for longer without having to stop because you have a dry mouth.
Wigging It Up - for people who like role play, wearing a wig is enormous fun. Usually the woman gets to flounce around with preposterously long curls or twirl away with a sleek bob. Especially if you have short hair, letting your new long hair drape silkily across his body will be very sexy.
