Taking a shower together?

I’ve been a new ish relationship for awhile now, we had sex and have the most amazing sex life as well. In my past relationship I hated taking a shower with my s/o because he was a water hog and it was never romantic. Shower sex is never what it is etc. Well the new man I’m seeing has been wanting to take a shower with me, he knows I hate sharing the shower but he says I can have all the water and he just wants to enjoy me and would love for my shower water to just splash on him (lol🙈) I have a very nice body/ish but I think I’m just more self conscious to take a shower with him, how can I get over it and just enjoy whatever comes our way and just let him take a shower with me.
