Possible reasons and problems of Aegon's co*k being destroyed

So, Aegon does not have cock anymore, he cant have children. At this point either Helaena is pregnant with him, or someone else's bastard, or he will be cancelled. And also, we know that in the future Aegon will be going to marry Cassandra Baratheon as reward for Borros help and to obtain heir. Why he will be doing that if he cant have heir anymore? Or Condal will say just another trash about green propaganda. Even if he marries just for convincing other people, there is a high probability that someone will find out about his problem.
About the reasons writers did that, I think the reason is that green team argument is Aegon being male. For most of people, the only difference is just presence of cock. Now they will say that Aegon's claim was having cock and now Aegon has not cock and etc. It's just type of mocking his character.
