ok answer for question one usually right after that answer to questin 2 sometimes it takes less time to orgasm the second a third time and it does hurt less you answer to question 3 yes yo will reach orgasm an last but not least no th squirting thing is not pee it is cum
I think that you still haven't learned how to find your gspot. Or at least, you are scared because your hubby found it.
Look, it is normal to have those feelings and I do understand that you are scared that you are going to pee all around, but that happens when you are about to cum.
The main reason why you are scared of this is because you are still not relaxed when you are being intimate with your husband for some reason.
Look, it seems to me that your husband is really trying to please you and you should relax totally.
There is no reason for you to be uncomfortable because of this - that is all normal and I believe that you are going to like it once it happens to you.
