How do I tease myself in the bathroom?

I’m female, bisexual and submissive and I am challenging myself to not pleasure my pussy and make myself as horny as possible for a week since it’s my first time, for someone who still lives with their parents, shower time is the most private time I have,and I want to make good of this time and make myself so wet,aroused and horny that my whole body trembles and all whiny, I want to tease myself,but not give myself the slightest pleasure,so uh..how do I do that? Especially when just running warm water down my cunt and clit it can already relieve a bit of my arousal PS:this is my first post,I feel so ashamed of myself having to ask for advice,well,what can I do?
