1)Do you know how many guys your wife or girlfriend has slept with prior to meeting you?
yes
2)If so, what is the number?
5
3)Do you think she is telling you the truth?
No...
4)Does the number of guys she slept with matter to you?
The number doesn't matter, not being honest does.
5)Do you ever discuss her past sex life with her? I.e. cock size she has had, etc.?
Only about the last guy she dated. She was sleeping with both of us for a few weeks, not at the same time. Although her ex did ask me to do a threesome. I told him I didn't think she would go for that. Anyway, She was getting it twice a day... 
for a few weeks.
I am very interested in getting some feedback. Thanks for your honest answers.
