good but still lacking essential information as effect of sexual activities on nervous system, memory or other intellectual abilities

I think you need to get your calories right - 260 calories for 10 minutes of kissing which means if you kiss for 30 minutes you would have burnt 780 calories! While having "vigorous sex" you only burn 150 calories in 30 minutes... Hmmmm 520 less than kissing for 30 minutes.

I guess I will just be kissing from now on :)

very interesting and new.

The ear of female touch with tongue also activate sex activity

in response to sam, yes girls can ejaculate and it is not a camera gimmick.And it is a personal experience i'm sharing with you here, but there is so much more info attached with it some are, she needs to be completely open with you and your foreplay needs to be at least 40 minutes although every one is diff. trick is the g spot + clitoris but do not press too hard or too soft..and look for your partners response and for god sakes look her in the eye!!!!!!!!

Couple should engage in sexual intercourse almost everyday, the exception could be made only if the lady is in mestruration period. My girlfriend lost her virginity to me while she was 17 years, at least she could enjoy sex. Your information is truly helping.

i am married for about 14 years and still i havent experienced of having an orgasm, so whats the problem with me.. please i need some advice and help from others

There seems to be confusion if the girls like men can ejaculate if given proper orgasm - I have seen some videos but not sure if they were faked or camera trick. Is it true that girls have two types of orgasms — one in the clitoris, and one in the vagina?
