Is it normal that i am horny in the bath tub

Yes, you can be horny anywhere dogg. On the roof tops, under the bridge, in the kitchen whippin up banana cream pie!

I would prefer not to bathe in my cum.

It is unclear if you are male or female. If male, you're in no danger as long as you don't introduce your cock into the spigot, drain, etc.

If you are female, pleasure yourself as you wish - but avoid introducing soapy appendages (e.g., fingers) into your cunt, as the pH of the soap will be more acidic than the pH of your secretions - and may cause immediate irritation, and possible UTIs (Urinary Tract Infections).

Aslong as you ain't gettting anyone pregnants

So ??

to use a soapy hand hot

Okay what should I say
