DH was pretty sexually inexperienced apart from the odd fairly unsuccessful fumble before we met. He was also brought up by really strict and oppressive parents. We have been together for 14 years now and things have moved on a lot since then. Sex is really good apart from when I initiate something different where I think he loses his confidence and his erection becomes a bit soft (sorry tmi). I don't draw attention to it, but it does stop me from trying new things which is a shame. I don't want to make this into an issue as we do have a good sex life even if it is a bit samey.
