I already gave you an answer to this. However if you have “dated” this girl for 3 weeks and still haven’t kissed her then you are clearly a eunuch. By this point she must either know this or suspect this. If she knows this it doesn’t matter if you kiss her because she is just using you to make herself look like she’s not a lesbian. If she suspects this she will be trying to find somebody better.

If only to protect the secret of your castration you will need to ball up and kiss her.
