Warning: Shower adventures ahead

Emily • I like mac n cheese better than most people
I stay at my boyfriend's place a couple times a week and we both have busy schedules where we have to get up really early ( like 5 am) so showering there would allow us to spend more time together. It was his idea actually. I love the idea.
No shower sex because that sounds difficult and dangerous lol. Just foreplay.  I just want to know what i'm gettin myself into. Any tips? What to expect? What to avoid? (Ex: i've heard blowjobs in a shower are awful because there's water everywhere, all over your face, blah blah blah)
