What helped you with your sex life after having kids while breastfeeding

We are first time parents to an almost 5 month old. breastfeeding and expressed milk bottle fed. On top of having no time I have no sex drive either. We have sex maybe once every week sometimes two honestly not sure how often I hope it’s not longer than that. When we do have sex I can never stay aroused long enough for my husband to finish. My husband is understanding but I feel really bad. We have tried lube, don’t remember which one it was Ik it’s water based but wasn’t our cup of tea. Made things feel sticky in an uncomfortable way :/ what have y’all find helped you guys?

Edit: sometimes, i feel so bad for saying it because lol he’s not bad in bed but half the time I want it to be done for I just am not in the mood for sex almost ever and a lot of times I’m just not into it at the moment
