I am not in your group (actually due in March) but I couldn't help but notice this post becuase I am a sexual wellness educator who is moving into specializing- helping couples get through pregnancy and beyond. I am going to try and write this as PG as possible, but sometimes hard to do with this topic, so forgive me.
I was really, really sick during my first trimester too. I slept most of the day and lost most of my desire too. I too am a highly sensual person so this was a very new experience. But my partner was great! Every day he did gentle nipple stimulation which helped me produce more oxytocin and he gave me sensual massages without pressuring me to do anything that I didn't want to do. I worked on my end to keep my sensual energy high by doing self touch and self care. And those Kegel are also good to help you keep your sensual self in shape.
I found that during my second trimester my drive returned with vigor. That may or may not be the case for you, but it is usually when you feel best and sexiest. Plus you are getting a lot of extra blood flow down there which increases your chances for great orgasms.
Most important though is communication with your partner. Is he okay taking care of himself until you feel better? Is he okay with making love to you gently, and doing the majority of the work for awhile? Remind him that it isn't forever. Also there are lots of things that you can do that aren't BJ or Intercourse- massage, mutual self pleasuring, kissing, nipple stimulation etc. It is vital to work all of this out before the postpartum period. There are many couples (85% of my practice is this) who never recover their sex lives after the birth of a child. It is good to create a plan now, to talk about this now. How will both of you get your needs met?
It is important that he not pressure you (sounds like he is doing great so far) as this creates resentment on your part. And it is important that you find ways to nurture him, so that he won't resent you. That is one of the biggest turn offs and ultimately kills sensual wellness- RESENTMENT.
Hope that helps. Glad you all are talking about this as there are many people who feel alone around this subject.
