What do I do if my daughter caught me masturbating?

I was taking my nightly bath and my daughter walked in to grab her toothbrush and other toiletries, as she was sleeping at a friends house, and I was pleasuring myself, thinking that would be private enough, and she walked in and saw me. Now I'm not sure if I should talk to her about it, or leave it alone? I know either way it's going to be awkward, but I'm not sure what to do? Please help.I'm really embarred. Thank you in advance, and please be courteous.
