My boyfriend says that I don't 'feel' the same when we have sex like I'm 'loose' or 'stretched' I'm not cheating or using any sex toys can you tell what can cause that?

Do your kegels, that will bridge the gap in no time. Try squeezing them during intercourse at times, al muscles will lose something if they are not exercised. Childbirth is often a cause of the PC muscles stretching so to speak. Just give them a good workout several times a day for several seconds at a time. It will help but the results won't be instant. The other explanation is that maybe he is doing it with someone that is tighter or his thing is shrinking... j/k.

I think this is bull... He is just trying to make excuses for alternative ideas sexually. He may be building up to asking you to do other things. Also a way to put the blame on you for his inability to perform. Don't take on his guilt. Women do sometimes relax a bit but not to the point that you cannot satisfy a man. I have had 5 children and have had many sexual partners... NONE complained about being loose. Cathy
