Let me understand this, you want to loose interest in SEX!!! WOW you need to think about what you're saying. You don't want to give up sex, I love sex! You should see a sex therapist.
I only wish i had that desire!!!! I am the opposite to ur situation. I found that my sex drive rose after my first baby, however after the second baby, i lost it again. Ur husband should be pleased. On a more seriouse note, if u feel like having sex every second of the day or u feel ur appetite for sex is too much for ur husband to handle, you may consider seeking therapy or at least seeking advice from a counselor or Gp advise. In the mean time ENJOY IT!!!!!
