As much as you can buddy cause if shit goes wrong, there might be a present waiting for u after maybe 9 months.

You must have a huge one if you can hold it in your dick for minutes, i suggest you keep it in your balls first and release whenever you have to. I have a 4cm dick and when i hold it in my dick i usually cum first but when i keep it in my balls i last long. You're welcome.

Well you can't but you need to make sure she cums
