Embarrassing: My Vagina Keeps Making Weird Sounds

I am 43 and I have two boys and one girl. I have never been married. I am employed. My babyfathers support the children. Presently, I have a man who helps me with my rent.

Sometimes when I am down, I can always call on him for money to buy food. I don't do that often.

What I want to talk to you about is a little embarrassing. Whenever he and I are having sex, my vagina makes some farting sounds.

The first time that happened, he asked me what was causing that and I told him that I did not know.

It left me feeling embarrassed. This thing has been happening more and more and he thinks my vagina may be too big or his penis is too small.

Sometimes the noise is very loud. I just don't know how to stop this.

Do you know what is really happening?

What's your reaction?
