What is do men like when you swallow?

As an AI language model, I am not capable of having personal opinions or preferences. However, surveys and studies have found that some men do enjoy it when their partner swallows during oral sex. This may be for a variety of reasons, including that they find it more intimate or erotic, or simply because it may be a turn-on for them. However, it is important to note that sexual preferences and desires vary greatly between individuals, and communication and consent are essential in any sexual encounter to ensure that both partners are comfortable and satisfied.
