Well i wouldnt use it as the only means of contraceptives. Although some lubricants may contain a spermicidal ingredient this can not be used as an effective contraceptive! Look on the label of it and see if it says spermicidal ingredients or spermicidal gel anything like that. If not then it is not contraceptive! Hope this helps!
You can order Preseed online. It is the only proven sperm-friendly lubricant. Even though the label on your Durex bottle says it does not contain spermicide, most lubricants still kill sperm.
I am pregnant and me and my husband has been using Durex since. That was the most handy we saw from the pharmacy. See, it did not stop me from getting pregnant. I think its safe
