I lost my virginity on Wed and there was blood. I went to the bathroom about 45 min after and I felt stinging but both went away after about a day and a half.

I had sex again on Sat and I am bleeding again. I have very minor stinging (not really painful but it's just noticeable). We used lubricated latex condoms both times.

How many times will it be before I stop bleeding when having sex? Am I having a reaction to the condom? Why does it sting?

How old are you Violet?

Bleeding can be caused by either your hymen breaking or rather rough sex, for you I am guessing the first of the two.

I would hold off an having sex again for a week or so until that area can heal, if you had sex only a few days after your first time it may have irriated it and hence the bleeding again.

Latex allergies are more common than you might think as well, I personally have to use non-latex as well as a special brand of lubricant

I am 26 years old. The bleeding went away a lot quicker the second time then it did the first. What other indications would I have if it were the latex? He had stimulated me in other ways so I thought I was pretty well lubricated but the first time hurt very badly until we found a rhythm. The second time only hurt for a moment when he first entered me. What kind of lubricant do you have to use?

I can't remember the name of mine (haven't bought for quite some time) but it was something like alcigel or alcogel or something similar.
My doctor recommended the specific brand, so just ask your Gp about it, don't be embarrassed, they have heard it all.

The ones for sensitive skin can be a little expensive but a little goes a long way.

For me I knew it was an allergic reaction when my partner used a tube of regular lubricant as a massage oil on my back (we were out of proper oil) an my whole back turned bright red and burnt.
To test the lubricant you could try rubbing a little inside your elbow and see if you get a reaction.
