<human>: Summarize the given text in a few sentences.

Hi all, 

I [22F] have recently started going on dates with a guy in my graduate school program [21M] (please see below for more details), and he is very curious about my past relationships. Normally, I would be be perfectly fine talking about my history; however, he is very much the traditional, conservative type who frowns upon people who hook up and have non-long-term relationships... both of which I've done... Is telling the truth about the past really necessary? My mentality is that, as long as I've been faithful in closed, long-term relationships, the details of who I dated and hooked up with shouldn't matter...
<bot>: The guy who I'm seeing is really curious about my past but I know he would disapprove of it... If I'm interested in continuing to see him, should I tell him the truth?
