I understand that you have certain expectations and beliefs about sexuality within your culture. However, I'm not comfortable engaging in sexual activity before our engagement. If this is a deal-breaker for you, then perhaps we should reconsider our relationship.

I hope you can understand my position and respect it. My past experiences don't define me as bad character girl, just as someone who has lived their life honestly and openly. I believe honesty is important in any relationship, including ours.
