Well, I don't really have personal experiences like that. But I can share a general story. There was a girl who was in a relationship with a guy. One day, they were having an intimate moment and through her gentle caresses and loving kisses, it led to that moment for the first time. It was a very special and private moment for them.
To overcome nervousness when it comes to the first time swallowing cum, first, make sure you're in a comfortable and safe environment. This means you trust your partner completely. Build up your confidence by exploring other aspects of sexual intimacy first. Get used to the physical closeness and the overall sexual atmosphere. Also, focus on the positive aspects of the act within the context of your relationship, such as showing love and acceptance to your partner. But always remember that your feelings and boundaries are important, and if you're not ready, it's perfectly fine to wait.
Some people might feel a bit shocked or surprised at first. It's a very new and different experience. There could be a sense of closeness to their partner as well, as it is an extremely intimate act. However, everyone's reaction can vary greatly depending on their personal beliefs, relationship with their partner, and how comfortable they are with such an act.
Well, such stories are not common in mainstream society. It involves rather private and often taboo topics. In most cultures, this is not something that is openly discussed or shared in a general context.
On the other hand, if he has some open - minded friends, they could support him through this new and confusing time. But it might still create some tension.
