When showering with someone for the first time, there are a few things you should be aware of to ensure a comfortable and enjoyable experience for both of you:

1. Communication: Discuss boundaries and comfort levels beforehand. Talk openly about what you feel comfortable with and what you don't. Clear communication helps avoid any misunderstandings or discomfort during the shower.

2. Privacy: Remember that everyone has their own comfort levels when it comes to being naked or being intimate in shared spaces. Make sure you respect each other's privacy and boundaries during the shower. If someone prefers to have a certain level of privacy, accommodate and respect their wishes.

3. Safety: Pay attention to the temperature of the water, making sure it's not too hot or cold. Be cautious with slippery surfaces to avoid accidents. Additionally, be mindful of any allergies or sensitivities your partner may have to certain shower products.

4. Respect personal space: Give each other enough room when showering together. It's important to be aware of personal space and not overcrowd or invade someone's personal comfort zone.

5. Enjoy the experience: Showering together can be a bonding and intimate experience. Embrace the opportunity to connect with each other, have fun, and enjoy the physical closeness. Share a laugh, wash each other's hair, or explore the sensual aspect if both parties are consenting and comfortable.

Remember, the key is communication, respect, and consent. By being aware of these factors and considering each other's comfort, the experience can be enjoyable and strengthen your connection with your partner.
