If you are married or has a boyfriend, tell him to talk to that man. If not, then tell him to stop it because it is an actual crime. I do not know where you live, but public indecency is a crime in almost every country. Unless if you live in a shit hole country somewhere in Africa, he is commiting a crime.
Since you don't want to get her involved, the easiest way would be to actually threaten and be frank to him. Just threatening is fine, as long as he stops (since you don't want to involve her) . If he still doesn't stop...talk to her in a joking way about his habits or about how he acts. Either way, she should know. Unless if he is just an open all door sort of guy, pretty sure he wants to cheat on her with you. I don't know about you, but I'd like to know if my significant other is doing that.
next time please please scream. if u dont he'll never stop since he feel u are intimidated. you are not helping his wife and god knows how long has he been doing it and maybe you are not the only one. predator likes someone they can control and we'll never know if he decides to do something worst. and tell someone close to you about this.
Sorry, u're case and my case was different, cz u're boyfriend I think he do it unintentionally,, maybe coz its a habit,
While in my " neighbor " case,, he do it intentionally, cz he just do it when his wife not at home..
And right now I feel like shit ...
And I afraid no one will hear me and doesn't believe me, cz on the surface, he was a kind and caring man..
u just scream like "arghhhh" to scare the pervert and attract others. sure it will be awkward afterward but it will remind the pervert that you arent scared easily. make sure to take extra precautions when u are alone. try to avoid being alone in dangerous area. and again tell someone. if anything happen (god forbid) at least he/she knows.
What will you do, when u're neighbor's husband, go out to great u, with just a towel, and no underwear, and it's like he Intentionally showing "it"..
And he do it often...
Honestly, it's really disgusting and disturbing,
Like wtf.. and I want to scream and get angry,,
But I don't want to hurt the wife, cz she was someone I really know..
Help please...
Because right now,I really Feel disgusted...
