Why does her virgina change in size?

Hello

My girlfriend and I have been dating for just over a year. I've never had this problem before. We been sleeping together for about 6 months now but a week ago it was different. Whenever I go down on her after we haven't done anything sexual for...

about a week, her virgina is tight. But last weekend, we never done anything for about 5 days and I went down on her and I hadn't touched her there at all before I did, I went straight down there and she was already all loose.

We went partying the night before until 4 in the morning and I dropped her off at home and the next day we done what I explained above and it was different. Do you think she done things with another guy or done things to herself? Or could I just be other reasons and if so what are they?

Thanks

Well, there could be a number of reasons why she was loose, you are right she could have slept with someone else, or she could have masturbated, that is when you question yourself. Am I giving her a reason to cheat? Am I doing what she wants me to? So, basically do she have a reason to cheat? Just simply be blunt about it and ask her what happened. Don't ask in a mean way just simply ask and act like you are concerned...

This is NOT a way to tell if she cheated!! THERE ARE SO MANY REASONS AHE COULD BE LOOSE! to name a few....1.shes menstruating 2. she masturbated 3. she masturbated with a vibrator 4. she was shaving

Well i asked her about it. I told her not to take it the wrong way when i did ask and she said that she didn't masturbated and she has never cheated on me. This was on Saturday and she started her period yesterday. Is that possbily the reason?

Firstly i don't think she has cheated on me because i mean, she has at school (she's in matric) for the whole week and on Friday she was off so she can get her hair done, makeup for her matric farewell. She was with her mom the whole day. Then friday night we were together the whole night, i even dropped her off at home and i saw her the next morning at 8 o'clock and she was with me for the rest of the day.

Well i asked her about it. I told her not to take it the wrong way when i did ask and she said that she didn't masturbated and she has never cheated on me. This was on Saturday and she started her period yesterday(Monday). Is that possbily the reason? Also she has bee very stressed about her matric farewell and alot of other things. Also she recenty started taking the pill (been on it about 3 weeks now.) ??????

Also. She has been at school since Monday last week right, i see her every night. Her matric farewell was on Friday and she was getting her hair done and makeup and getting ready ect, and she was with her mom on Friday so i don't think she couldv'e even tried cheating on me, i know she won't but i'm still worried. Friday night we were together the whole night and i dropped her off at home at 3 in the morning and then saw her at 8 the same morning. So i don't think she cheated on me. Although she did start her period yesterday (monday) and she also only started taking the pill 1 month ago. Are these perhaps reasons?
