Help ladies I honestly don't want any judgements

So I kinda want to bring it up to my husband to spice up out marriage in the bedroom as we are trying for our first baby. We have been trying over a year and pretty much the same position all the time. I have brought up to him in the last about doing different positions. (Please no judgements) but he's not small but not very big so it's hard to do a lot of position he doesn't think anyways.. he also has trouble staying hard. (So we dont always last long) He's embarrassed to talk to the doctor about it. So what are some ways I can possibly spice it up?
