Tips on masturbating?

I still live with parents so it's hard for me to stay in the bathroom too long. Don't have a shower head and can't bring toys cuz they'll for sure be found out 🤦🏾‍♀️

Oh, I do have my own room thankfully. Only reason I share this to express how much I need to get off but can't because I'll easily look suspicious.

I've tried using 2 fingers but I get a little tense. Any advice?
