Question for my fellow gay vers/bottom dudes...

I'm really only recently getting into anal play and wanted to ask this here rather than in a mainly cis gay guy sub. I wanna know, is there a way I can have the ability to spontaneously jerk off and do butt stuff by myself without having to always be douching? Sometimes I don't have the damn time for that and I'm horny near constantly lmao (3 weeks on T!) but I don't wanna accidentally make a mess 💀 Any advice on "staying ready" appreciated!
