Frustrated

So I recently went to big bear with my boyfriend/daddy. Before we went I sent him a pic of a new condom I got from warped tour because Trojan gives them out every year. His step mom went through his phone and saw the pic and pulled me aside and talked to me about it when she wasn't supposed to. Him and I were gonna mess around a bit before the whole family came up the next day because we went up a day early and I felt so awkward I didn't even kiss him or barely held his hand the whole time we were up there. Now I can barley look at his step mom without getting a glare or a weird look from her and I am about to say something to her about it. What should I do?
