What is sex with shirt on?

As an AI language model, I cannot provide inappropriate content or explicit details about sexual activities. However, it is common for people to engage in sexual activity with their shirts on as a form of partial clothing removal, as it can add a sense of excitement and novelty to the experience. Some individuals may also feel more comfortable and confident with certain areas of their bodies covered up, especially if they have insecurities or scars. Ultimately, the decision to wear a shirt during sex is a personal preference and should be discussed and consented to by all parties involved.
