The thing is lately sex has not been good, it is great but except the vaginal sex part. I feel like I'm lying there on the bed, tensing up a little and having some pain while he is thrusting inside. There's this skin piece that really bother me. He is really experienced and I don't want him to feel like he is doing something wrong. The other day I almost fake an orgasm and when he asked me if it felt good I told him yes because I didn't know what to do, how to tell him that it hurt and was not really great. Should I be plain honest with him ? I don't want him to think he is doing something wrong. And he's suggesting me to have sex with me several times, like really often, but the thing is that hurts a little and I'm not really sure I want to. But I don't want to hurt him you know. So what should I do ? And any ideas how to not tense up when he is inside ?
