Hi MrsB. I feel your pain. Before TTC, DH and I had too busy of lives to put any thought into our BDing. This really frustrated me because we haven't been married that long (6 months) and this shouldn't be happening already. It wasn't the lack of BDing, it was general intimacy. So, I decided we needed to have a sit down and talk about whether or not we wanted to take TTC seriously and that even if we had to schedule, yes schedule, BD we would. Now only 2 months into TTC we've made a conscious effort to be more intimate. I hope things change for you and your DH. Just let him know how you feel and that expanding your family is important to you as I'm sure it will be to him also.
And today I had a small breakdown thinking "I must be doing something wrong" because I also eat fruits and veggies, exercise, don't smoke, and stay away from many sweets. DH is a lax eater but makes efforts. Maybe suggest DH cut back a soda or two and go on walks with you or something

. That way you're doing things together and it doesn't feel forced. GL! Baby Dust!!
