It's not a matter of lying. It's a matter of boundaries. What he is asking is none of his business at this point in the relationship. In asking you, he could be kinda bullying you. Trying to claim all the power in the relationship. Do you think he never sleeps with someone on a first date? I would think everyone who dates has at some point in their life.

Maybe it was on your mind and the conversation led that way. A male t of mine once told me that guys will ask for it, just to see what they can get away with. At the time, almost 20 years ago, i had very bad boundaries - i was still being bossed around by my mother, had not cut the cord yet - and his answer distressed me very much. I wanted men to do my boundary work for me.
