It's difficult to say if they are common. There could be a lot of guys who have had such an experience but are too shy or afraid to talk about it. Also, society's view on same - sex activities can greatly influence how often these stories are shared or even occur. Some places are more progressive and might make it seem more prevalent, but overall it's a complex matter that involves personal, social, and cultural aspects.
Sharing such stories is highly inappropriate and disrespectful. Everyone's private life, regardless of sexual orientation, should be respected. Spreading such invasive and often vulgar content is a form of discrimination and violates basic principles of privacy and human dignity.
Yes, in some coming - of - age novels, there might be stories about teen boys facing challenges and growing up experiences that could be related to'sucking' in the sense of struggling. For example, in 'The Catcher in the Rye', Holden Caulfield has a difficult time adjusting to the adult world and faces many setbacks which can be seen as a kind of'sucking' situation in his teen years.
If by'sucking' it means being involved in some unethical or unhygienic behavior, it's a serious matter. In a school or community setting, when teen boys are caught, it can lead to social ostracism and a need for counseling to correct their behavior.
No, it is not appropriate at all. A teen girl is in a stage of development and should be focused on positive things like education, building healthy friendships, and self - growth. Seeking such inappropriate stories is not in line with good moral and ethical values.
