I'm translating a hentai DeepL isn't being helpful. Can any of you translate some lines for me?

>>19822730 (OP)
This line too

>>19822734
and this one

>>19822730 (OP)
If you seat in toilet/if we sit in a private room it's fine
The first thing/the best thing is to masturbate the penis
>>19822734
I've told ya, I get erections in all kinds of places
>>19822736
So... I.../and...

Kinda hard without context

>>19822871
Thanks man, that first one was tripping me up and I needed backup on that second 1, with that I should be able to get the third.

What's this last one?
>>19822871
It comes one line before that if that adds context at all
