This strong, masculine actor made his debut in the erotic industry alongside his off-screen lover, Anna Malle, and can often be spotted acting alongside her in intimate moments (even agreeing to let her co-star with other males). Filmmakers appreciate Armstrong for his relaxed, comfortable attitude during shooting as well as his skill in eliciting top-notch displays of passion from Anna. Look in any film featuring her on the cover, and chances are you'll encounter this friendly hunk in a variety of steamy situations too.
