me and OH wasnt actually trying to concieve but we wasnt being safe either partly because i was told after my first baby i woouldnt be able to have another child, but everytime we made love we used the durex lube not KY it also says its not a spermicide and i dont know the facts if it kills sperm or not but i mangaged to concieve using it and we never do it wilthout lube as its more comfortable for me than if we dont use it, i would still go for the pre-seed just in case but it might be worth doing some research into other lubs and find out if they are ok to use whilst TTC x x
