5 months pregnant and SUPER horny?!?

Im about 5 months pregnant and so horny I almost can't stand it! The problem is my fiance is a firefighter and gone for 16 days on a fire =( so Im stuck! I also have this problem of feeling like I "didnt quite get there" if you know what I mean,which makes it even worse! Does anyone have any ideas,tips, or "ways to play" that may help? If you're pregnant or have been,bonus! HELP! lol
