During the last few weeks I feel permanent hunger (I am 17 week preggy now). Well, it's not that I only want to eat but it's more like sex hunger. My husband doesn't understand what's going on, although I told him it's just hormones. But is it alright? Is it safe to have sex up to 4 times a day? I can't help being so close not touching him. The last sex I had a nosebleed and I'm scared, maybe it's too much? Am I the one with this issue? If someone has been through this, please tell me how to cope with this. Thanks in advance!
