Well, it's hard to say if they are common. Everyone's first - time sexual experiences are very personal. Some twinks might be more open to sharing their stories, but there are also many who keep it private. In general, in the LGBTQ+ community, there are various experiences shared, but it doesn't mean that 'true first - time sex stories' are widespread in a sense that everyone has heard or can relate to all of them.
I don't think they are overly common. The concept of a 'true first - time sex story' is quite subjective. Each twink has their own unique journey. Some may have had a very positive first - time experience and be eager to share, while others may have had a negative or confusing one and choose to keep it to themselves. Also, not all twinks are part of a community where such stories are openly discussed, so overall, it's not a common thing.
They might not be as common as one would think. Just like in any group, the decision to share such personal stories varies from person to person. For twinks, there could be a lot of factors at play. Social stigma, personal values, and family background can all influence whether someone wants to tell their first - time sex story. So, it's not a common occurrence that we constantly hear these stories everywhere.
