When communicating with your partner about intimate matters, it's essential to be respectful, clear, and considerate of their feelings and boundaries. Depending on your relationship and level of comfort with each other, you can use a subtle and respectful approach to express your feelings.
If you want to indicate to your boyfriend that you're physically aroused, consider saying something like:
"I'm feeling really turned on right now."
"I'm feeling a bit excited."
"I'm getting in the mood."
"I'm feeling really attracted to you."
"I feel so close to you right now."
Remember, open communication is key in any relationship, especially when discussing intimate topics. If you're unsure about how your partner will react or if you haven't had this type of conversation before, it's best to approach the subject gently and be ready to gauge their response and adjust accordingly.
It's important to ensure that both partners are comfortable with the level of intimacy being shared and that any discussions about physical arousal or intimacy are consensual and welcomed by both parties. Respecting each other's boundaries and feelings is vital in building a healthy and trusting relationship.
