31 weeks pregnant with bad sleeping problems...please read embarrassed to even ask?

[kay2daz]

So this is my 3rd pregnancy and I've had the same problem with all my pregnancies....When I get tired and ready to lay down I get extremely horny....Like bad to the point that even if I masterbate nothing relieves this....I guess it's like how guys get blue balls and they say it's painful....well this is really painful...To the point that I can't sleep because of it....My husband has tried to help me out but as soon as I orgasim I'm just as horny again....It's only when I lay down to go to sleep and with this pregnancy it's much worse then the other two...To the point of insomnia....I'm not even sure if it's horniess...It's just a tingeling feeling down below, and like I said orgasims don't solve the problem....I've tried everything and nothing works...Since about 26 weeks I've only managed to get maybe 2 hours of sleep a night because of this problem...Do you know what this could be or what's going on with my body?? And if it's hormones why does this only happen at night?
No I'm sure it's not a yeast infection...The tingling feeling is internal....No itchiness or anything...Just like a rush of hormones I suppose...I just dont get why it happens every night when I go to lay down....Like I said, it's like I'm really horny but nothing can make that feeling go away....
