Hi all, I'm a newbie here. While I haven't tried sounds yet, I have used a thermometer to take my urethral temp. I have to say I found it stinging and intense at first and only went in about an inch or two. After I got used to the initial feeling, I found it very enjoyable and became quite excited. I got very erect and produced a lot of pre-ejaculate which really helped with the lube part as it is very slick. I really want to add sounds to my play someday.
