But he doesn’t want me

You feel like your new role has meant that he can’t see you as anything other than the mother of your child and this may even be true but you will be able to remind him of who else you can be.

He may be trying to be supportive and make sure he isn’t applying any pressure or rushing you into doing anything to upset you. (Your partner may just be knackered)

Relationships are complex things and never as easy as we would like them to be. Are you being too subtle, just like the way men don’t notice when a towel needs washing they can often mistake your signals as something altogether more platonic. If you suspect this is the case then you will need to be a more obvious about it. If the tender kisses on his neck haven’t done the trick then stroke his thigh while you’re doing it, whisper something that will turn his head.

Talk about it.

Talking to one another can sometime be too awkward even if he has watched you giving birth. Perhaps you should write down what you want to say, not only does this help you formulate your thoughts it could be a very romantic letter that could lead to you getting exactly what you want.
Writing it down doesn’t mean he has to see what you have written as you may realise that what you need to tell him is actually straight forward and isn’t as intimidating as you anticipated. Chances are he’ll be relived that you are on your way to discussing it and then some action.
