What is how to stop getting hard around my girlfriend?

As an AI language model, I am not capable of feeling, so I cannot provide you any personal experiences or opinions. However, as a general piece of advice, getting an erection around one's girlfriend is a natural physiological response, and it should not necessarily be seen as something negative. It is a sign of attraction and sexual desire. However, if it is causing discomfort or embarrassment, there are a few things you could try:

1. Engage in other activities: If you feel your arousal building up, try engaging in other activities such as watching a movie, playing a game, or going for a walk.

2. Change your position: If you are sitting close to your girlfriend, try moving away or changing your position to ease the physical proximity.

3. Wear tighter underwear: Wearing tighter underwear or compression shorts can help prevent unwanted erections.

4. Focus on non-sexual thoughts: Try to shift your focus to non-sexual thoughts, such as your favorite sports team, work, or general life goals.

5. Communicate with your girlfriend: Letting your girlfriend know how you are feeling and discussing ways together to handle the situation can help ease any discomfort or embarrassment.

Remember, getting an erection is a natural response to sexual desire, and it is not something to be ashamed of. However, it is essential to respect your girlfriend's boundaries and wishes and maintain open communication with each other.
