Why would cuddy choose house to do this?

currently on rewatch, in season 2 ep23, why does cuddy choose house to give her the injections on her butt? i mean she could have asked any other nurse, any one else in the hospital, any other female, someone who doesnt care enough to ask her why she needs these or what injections they are? Wouldnt she get uncomfortable being in that position in front of her male colleague who constantly makes snide remarks about her breast and butt? I just felt that was really intriguing. Anyone wanna share insights?

(PS - ik house is the only one who knows abt her getting sperm donors, maybe thats why, but still, it just feels like too much of a stretch).
