For background, I've been with DP for 3.5 years, I'm 32 and he is in his mid 40s. Our relationship is fantastic, he is kind, supportive, loyal, funny, attractive and we share the same taste in music, TV/films etc.
For the first few months of our relationship we had loads of sex (every night, and several times per weekend) after about 6 months it became like once a week, normally on a Friday or Saturday, which I wasn't complaining about but it did feel a little predictable.
Whenever we went on holiday or trips away I would always expect it to happen (because we were away!) and was usually disappointed. For example, we went on a two week Greek holiday and stayed in this beautiful hotel by the beach and DTD once and only because I asked 
Last year I got pregnant and sex was completely off the table for medical reasons (I bled heavily for the whole pg) and we haven't had sex since.
I had DD earlier this year (by c section, so no injuries) she is nearly 4 months old now and sleeps through the night but I'm still waiting despite numerous hints...(I've had my 8 week check up / I'm just off to my wax appointment). FWIW I take good care of myself and I've lost nearly all the baby weight.
We are normally really good at communicating except when it comes to this topic, but he is always much more open after a few drinks so the weekend before last after she had gone to sleep we had a glass of wine and a nice dinner and I plucked up the courage to bring it up. I told him I feel unattractive, unloved, unsexy etc. because there is no intimacy and he said none of those things are true, he loves me very much, and that me and DD are the best thing that's ever happened to him.
We have a beautiful baby, we are getting married in a few months and our relationship is so happy but my confidence is on the floor and I just can't sit around any longer and hope this gets better because I know it won't. I can hardly cancel the wedding over this but also I don't want to spend the rest of my life waiting for him to want to have sex again.
I don't know what to say to him to make him understand how much this is affecting me and what suggestions I can make to sort this out?
