<human>: Can you summarize the given text in a few sentences?

Let me start off by saying I'm in no way entitled to sex but I can't help but harbor resentment towards my GF for making me wait 2 years for sex when she didn't make her ex boyfriend wait as long (8 months, first time for her).

Sex isn't just about pleasure for me, but to show how much you love the person. (My 5 Love Language is Acts of Service and Physical Touch) We lightly talked about the topic, she said sex changes people (for the worse) her ex-boyfriend started acting "weird" after sex (I didn't ask what she meant by weird). Following that she said 2 years for us and ended the conversation.

Logically I understand why she wants to wait, because she is scared I'll change or start acting weird like her ex boyfriend. Her fears are understandable, but regardless I can't help but feel resentment.

I don't want to force her into it, but I can't get seem to get over it. Every time I think about it I tell myself "She must have really loved her ex boyfriend to do something so intimate with them but, have me wait 2 years". Again, logically I understand but emotionally I don't. Has anyone been in the same situation and overcame this feeling? Any advice in any form would be great. If you have to go ahead and be harsh.

Thank-you for the help.
