This is predatory behavior also known as 13 stepping. In an healthy group like my home group, it would not tolerated and those guys would get a rimming.
This is why we say to people in early sobriety: the men with the men and the women with the women
Start sitting next to the women and befriending them: steer clear of the guys, you can say hi and be friendly at the meeting but ANY invitation for outside activity is to be treated as highly suspicious (unless it's a gay man then it's cool to be friends).
Next time one of those creeps try to make a move on you just tell him:
If I am not mistaken, there are only TWELVE steps in AA.
They'll get the message
