Making innuendo about forking or dongles isn't sexism because they aren't belittling any specific gender. A man could be offended by that innuendo as much as a woman. If he had said, "women only exist to get forked by big dongles," that would be sexism because he would be belittling women. Don't confuse sexual for sexism.

Making innuendo jokes to a friend is not sexual harassment either. If he had said, "hey want to see my big dongle?" to the girl, that would be harassment because he would be making unwanted sexual comments towards her.

However, he just made a joke to a friend in private, and she overheard. I'm allowed to say anything I want to my friend, even if it may be inappropriate for the setting. She was free to think of him as a jerk, or even tweet "there's a jerk behind me." (Although I don't think there's anything wrong with making an innuendo joke to a buddy, but clearly she does.) Unfortunately, publicly shaming the guy for a private comment not meant for her was totally uncalled for and puts her on the wrong side of this mess.
