As long as you're not having marathons, that should be safe. Personally though I only feel comfortable having it out 3 hours per month (there's no clear word on if it's 3 hours per month, week, or day that's safe), so I only take it out if I absolutely have to. Luckily our actual intercourse time is pretty short, so between that and being an hour away we never add up to 3 hours per month. But once I did leave it out for 2 and a half hours, which scared the crap out of me. Always make sure to reinsert afterwards! I like to check myself every time I had sex to make sure I had no great escapes :-P
