i have and i have also asked girls to get tested befor i touch them as well. It gives you a chance to cool your jets and make a more rational decision and if they say no then they have something to hide that you dont want a piece of. If you dont get tested between all your partners you take a chance of passing things on that have a life long consequences and i bet you can only name what five or seven of the several dozen stds out there. ther are more than you know and a lot of em dont have any cure for them. be safe and sane. get tested have them tested. let lust cool down.
It depends, if you are asking him to do so because you know how many girls he's been with, he should not mind. If you are not sure about his history, you should ask him about that first..
