well talk with her why she is mad. and so. i mean is it because you are more than she can handle already? does she have confidence in you and think you want to be bigger to fuck other girls? or what is the reason? try to find out and then explain why you are actually doing it. is it because you want to be a better lover, get more self esteem, or looking bigger in the bathroom? i mean if i found out my girl did (don't know the english term) workouts so she would become more tight, i wouldn't mind. i mean the friction between the two things does make the sex more fun
my girlfriend knows? nope at the moment i don't have a girlfriend when i had she didn't know either. i don't talk so much about what im doing. i have done martialarts since a young age, and im weightlifting aswell, some girls actually go after guys who do these things, and therefore i don't tell anyone, if they find out its not a problem, i just don't need to tell it to them. unfortunately this also ended with a breakup once. out at night with my Girlfriend, and got threatened with a knife if i didn't give him my money. been teaching knife fight whole day long so i basicly broke his wrist +his nose and pulled his arm out of his elbow socket. police came took him bla bla. after my girlfriend was completely sure i was some kind of secret ninja soldier thingy who could kill people without touching them, and was actually afraid of me. point is: not always a good thing to tell everything. not always a good thing to keep it a secret.
but rule number 1: communication, communication, communication.
