Sex life postpartum

I am 6 days postpartum and I have a lot of anxiety about not being able to have sex with my husband for 6 weeks. I am breastfeeding exclusively so I’m already exhausted and not really feeling like my body is my own right now plus I’m still bleeding a little. My husband is not pressuring me, per se, but he will wake up with an erection and point it out and kind of complain that 6 weeks is such a long time and I just feel very anxious about the fact I can’t have sex with him and honestly don’t have energy for “anything else” either. I’m not trying to paint him in a bad light I’m sure it’s not his intention for me to feel this way. Just wanting to see if anyone could relate.
