I only had sex with 1 other man prior to dh and he suffered with premature ejaculation. Dh also had issues in previous relationships with a bit of performance anxiety leading to loosing his erections. Sounds like a recipe for disaster I know. However, he has overcome this with me and we do have a good sex life. But when we try anything new the issues come back a bit and he can loose his erection which i find quite off putting so tend to stick to what we know works iyswim.
We have a brilliant relationship otherwise. I fancy him a lot and I know he fancies me as he gets an erection when I am getting dressed in the morning, when we kiss etc. He treats me with respect and enjoy being together.
