Love between couple... Will you be able to make your woman feel comfortable with you... can you make her trust you... can you make her free from inhibitions ... so that she can let herself free ... or let loose herself... then there are other things ... Biggest asset you can have is train yourself in f0re play. There are some videos available for such things as massage (foot, hand, br-East, Y0ni). If you train yourself in those with PAITIENCE your woman LOVVVE you so much that she will be behind you then. These things you don't need to do in every session. If you are in a hurry or tired a quickie is OK. But then at least once a week if you can spend time on this for couple of hours its you are a winner.
Oh yeah! There is another thing. Most woman likes it longer (not the size but the session!). They like it at least 10-15 minutes. Can you keep yourself going longer than that. Yes you can. how? there are some yoga poses. learn them. hmmm....yoga gives very slow result. don't expect you do that exercise today and result by today/tomorrow. its not v-iagra. it takes months or years get accustom to some poses. these poses basically relaxes and strengthens the muscles which can keep you strong for longer in a natural way. Once you are master those poses you can see the result to hold yourself easily 30-45 mins. Other side effects of these poses are you become somewhat handsome (with wide chest etc), quite active in your work day, & healthy :)
