Postpartum sex advice

I am WAY postpartum, like 15 months postpartum; however, I am still breastfeeding twice a day (I plan to cut this out within the next 3-4 months while on summer vacation). With that being said, I only got my period back for the first time last week, and I have still severe vaginal dryness. For the first 10 minutes of sex, it’s like having sex for the first time again. We have to use an excessive amount of lube, and we have to take it so slow at first. It’s not only embarrassing, but painful at first and usually takes the initial excitement away from it all because it’s such a process. Has anyone else experienced this? I know that breastfeeding will cause dryness, but I’d hope by now since I’m only nursing twice a day, my body would begin getting back to normal. Thank you! ❤️
