Do I really have to ask why did he do it now?
What do you mean?
I asked him why he did it and he said: "because it was fun and I cant stop myself.
If someone wants to do something fun and it does not harm others, then let them be.
The guy is a virgin and loves to do it non-stop.
You should be more clear with your questions. Whatever he loves to do is his own business and if its personal you should consider not probing.
