<s>[INST] Hi, I am just over 4 months pregnant and have just begun to leak a bit from my breasts.  I know that can happen when women get further along in their pregnancy, so that is not what I am worried about.  I am wondering though, is it a problem if my husband sucks on my breasts during foreplay?  It probably only happens about twice a week. [/INST] Hello and I hope I can help you today. It is true it is not harmful to have early lactation during pregnancy. Many women even make some milk from repeated nipple stimulation who are not pregnant. Certainly it is not harmful for anyone to ingest breast milk, and if you and your husband enjoy that type of foreplay it is no problem. The only issue may be in later pregnancy you may get uterine contractions with nipple stimulation, as it produces natural piton to be released in your body. So if you get any uterine contractions (if you are not full term) it might be beneficial to avoid it then. Regular sexual activity is not harmful during pregnancy as long as you have no bleeding or pain. I hope I was able to answer your question and that this advice was helpful. Best wishes for the rest of the pregnancy,  </s>
