I sat down and had a talk with my DH about this.
Before we actually got pregnant, we had practically fetishized pregnant sex. We would talk about it, sometimes pretend, etc.
(We're addicts as well, and went at it almost every night.)
But after we really got pregnant, sex life just died immediately. I wasn't interested because I was afraid (DH is very well-endowed). And DH wasn't pushing for it anymore. I started to feel kind of lonely and miss it. I wanted it, but I was scared.
Finally, I talked to DH about it. I told him I was worried, but that by that point we were already 5 weeks. We had been going at it before I knew I was pregnant, and that was arguably the most sensitive time, so if the baby survived that and sex is supposed to be safe, I was willing to get over it. I asked him what he was feeling about sex.
He said it was kind of weird knowing that there was actually a baby in there. He also said he had a feeling of accomplishment now that we were pregnant. that he didn't feel the drive to keep going. But mostly, he expressed some feelings of loneliness. I was on BnB talking to people who had been through everything before, making friends here, finding all the information I needed and the answers to my questions. But he felt like he didn't have anywhere to go with his questions. Didn't have anyone to talk to because we decided we weren't telling anyone we know IRL yet. He felt jealous and lonely that I had all these people and friends to talk to, and he didn't have anyone.
So I promised him that I would share more with him, that we would find more answers out together, and reminded him that I loved him and that we were partners in this, and we did this together. I also told him he could tell someone if he wanted to, but he said that he felt better after talking. Things have been a lot better since, and our sex drives are completely back! We still don't do it as often as we did before we got pregnant, but we are more cheeky with each other, and have sex maybe once every other night or every two nights instead of every night.
Our appointment is tomorrow, and if all goes well, we have decided we would each tell three people we know IRL. His best friend from college has a 1-year-old son, so I think he'll really feel tons better then. He never really had a stable father figure, so he has expressed worries that he didn't know how to be a dad, and feels like once he talks to his friend, he'll feel much better.
