Quoting Mommy's Miracle:“ Any advice would be appreciated.. My fiance' and I have been together for a little over 3 years and ... [snip!] ... more and more insecure. I just feel like I turn him off because my increasing size, I am just so confused and feel so alone.”
it is totally normal for men to look at porn, unlike women who often masterbate for pleasure, men often use masterbation as a way to relieve stress and tension. The act causes them to feel more relaxed. Many men masterbate more while there SO is pregnant. Don't feel insecure about it. Its not you in the least. I sure he's still as attracted to you as ever, only in a different way and probably doesnt know how to express it or how he feels. Personally I just let my hubby dont his deed and leave it at that.My SO is alwaysmore relaxed after and appreciates that I dont bug him about it.Be open with him about it, but try not to be confronting.
Remember your hormones are different, men react when womens hormones change. Many men have trouble dealing with the hormonal imbalance and shy away from the women during pregnancy. Keep the communication lines open and welcome him to express his feelings with open arms, open mind and an open loving heart.
