<human>: I met my girlfriend a few months back. I'm typically shy and introverted. I don't have much confidence in women and this is only my 2nd girlfriend. 

She keeps prodding about my previous girlfriends but am too afraid to tell her the truth as she might see me as either weird or a loser. I just tell her I had casual flings in the past which isn't really lying.

I've seen over 30 escorts in my 20's which no one really knows about. I am disease free as I check all the time.

Should I tell her the truth? 
Should I just tell her to leave it in the past? Will she judge me and break things off? I like this girl a lot..

Provide a brief overview of the text.
<bot>: Lack of relationships due to being shy and introverted, seen many escorts, should I tell the girlfriend about my sexual history?
