I have been with dh 12 years. When we first got together he had problems with getting a full erection and also with ejaculating inside me. I found this frustrating but we didn't talk much about it and things gradually improved so he could get and maintain an erection and come inside me. Very rarely now he has episodes where he struggles to get a full erection but with persistence manages. This has basically killed any sense of adventure sexually in me as I worry it will put DH off and he won't be able to perform. I have become boring and lazy in bed because we do things the same way and I have lost confidence too. Generally as soon as DH has an erection he wants to have sex as I am sure he is worried about loosing it. Luckily he is able to keep going for a while so it is normally satisfying but I am saddened by the lack of variety and spontaneity and our inability to talk about sex. I'd like to change things but not destroy it altogether. Where do I start?
