Using an erotic toy is not a bad thing. Remember to use proper hygiene measures and store it in a proper place to avoid contamination or damage.
This! Hygiene hermeticism is key: #1
A tip I can suggest is grab a bar of soap especially if it leaves behind a lot of soap. Lather the toy heavily and leave it for 40-60 seconds(1 Mississippi etc.etc.) count it out. If you want purchase one of those cheap silk antibacterial soaps and use it for just your toys.
BTW O.P. by any chance have you been curious on prostate massaging toys? Such as Aneros, Njoy Pure Wand etc.etc.
Excuse me if I'm disrespecting you, insinuating your sexuality. But a lot of straight men love prostate play especially when they rewire their system and experience various sensations ranging into multiple full body super orgasms. Also ever considered getting into nipple play? nipplegasms are a thing and some men can experience orgasms more powerful than prostatic/penile orgasm, it's rare but it happens.
You gotta play with your nipples for quite a few days for several hours a day to rewire your system. In fact with the Aneros toys many men state play with your nipples cause that is part of the adventure.
They sell both manual i.e. using your hand or anal muscles like the PC muscle and also vibrating ones.
BTW don't forget to study kegel exercises and perform kegels throughout your day quality over quantity at first. Try and do like 3-5 kegel sets per day until you develop a routine. Stuck at the redlight in your car pump out a few kegels. Waiting at the Dentist office do some kegel.
It will help you with various things.
