<human>: Give me a shortened version of the text

I have been dating my girlfriend "Susan" now for 6 months and we couldn't be a better match for each other.  Perfect personality match, similar life goals, both are intelligent and well read, she loves me pieces and shows it in every positive way possible, and we are even from the same city. Life is great and I love the girl!!!

The PROBLEM is my dumbass self having the "past" talk and I found out that she had a sexual relationship with 2 men FAR older than her.  Susan had been with a man that is 37 and another that was 34.  One was a consistent hookup for 9 months.  This knowledge was overlooked when we first started dating, but now that we are more serious I don't know if I can get over this and am struggling to get over how disturbing it is.

It disturbs me when I see someone around 35 + talking to her as I cannot help but imagine the age discrepancy of a 19 yo Susan having sex with a 37 year old that is my girlfriend....It just makes me physically ill to think about and has turned my off completely.

I realize that the "past is the past" and I do not make her feel guilty about it but I have told her how seriously uncomfortable I am about it and I am having a REALLY hard time getting over it and am wondering if I even can.

I do have a history of having thoughts that are tough to get out of my head when things are disturbing like this and am wondering if I will ever get over it.

PLEASE anyone with advice or comments as to how you would feel knowing your respective partners had slept with men/women twice their age before they met you at such a young age?  Would it disturb you?  Could you look past it?  How can I re-frame or how can I get over this??
