Im not sure if we have the same problem Lucky, but i always have to make myself cum too. I have never cum from actual penetration (something i have been told isn't actually as odd a you might think) and although i can be on the absolute edge of release nothing makes me cum but my own hand - and even then in my own time - not on demand (which i hate so much as i would so love to do that for my master). I have a theory about not being able to cum when im with my master - i think it may be a certain amount of guilt, as my husband doesnt know about him and it makes me feel guilty everytime i meet him - i cant even cum for my master at all!!! Not even one time! He says its ok - but i find it humiliating as i want to please him more than anything! I even make myself cum for my husband - who really enjoys watching me and after 20yrs of marriage is used to my inability to be brought off by a cock inside me. We had a threesome with a friend of his years ago and at the time i was curious if he would be able to make me cum - but fantastic as it was to feel two cocks inside me i still didnt - so, lucky, i have no answer for you, just a bit of reassurance that i dont think there is any underlying reason for our problem, just that some women are built differently - my orgasms - when i give them to myself are sometimes earth shattering to the extreme and my husband says that to watch that is my gift to him (but it doesnt always make me feel better about myself) but after this long ive gotten used to it!! Sorry Lucky, what started as a quick reply turned into an epic, but i hope it has helped in some way. xxx
