Does anyone have the problem of having sex so much that it puts wear and tear on yourself? The girl I've been seeing recently likes sex so much that I can keep going and going and she just keeps wanting more. But I put so much into it that I have to sleep the entire day the next day because it wears me out. I'm not talking about a quick hit of good hard sex. I'm talking about hours and hours of sex, kissing, sucking, and totally sweating all over each other and burning up the entire time. I take Cialis so I can last a long time, I usually have a hard time getting it up if I don't take it. But when I do take it I can stay hard for quite a while. I can stay hard inside her for almost an hour and still never cum, that's what keeps me hard. Usually girls can't take penetration for more than half an hour. But this girl just keeps moaning and begging for more, saying things like "yes", "harder". And when I'm finished, I'll just do things like give her oral, dirty cuddling, and some kissing and sucking in all the most sensitive spots. Then my jaw becomes sore for the next few days from all the sucking. I take ibuprofen for my jaw which kind of works, but it can't be a good thing to keep taking it. I guess I just can't see her every day.
