If i saw her naked i will try to get her say yes to sex... i need the conection with her...

It is normal to have sexual thoughts about your sister. The question is acting on that.

If you don't want to go to hell, you wouldnt want to do it with her (incest is a bitch huh)

if ur a guy its normal nomatter who the girl is if u saw her naked ur going to thiink sexual

By now she's 18 and I think old enough to make decisions. I would hope they had a chance to talk about it and have had sex. Birth control is optional, my brother and I don't use it. Up to you.

What a predickament! I know if I was in your shoes I would be hitting her up for a piece of puss. I'm sorry, but I really don't know what to advise you. I agree that you do have a serious problem on your hands. Maybe that is the answer - take yourself in hand. There is nothing wrong with you at all. You are a perfectly normal boy. I think - maybe you should just masturbate and get it out of your system. Don't beat yourself up tho for getting a hard-onm for your sis! You simply can not help that. It is just nature. Don't freak either. You could talk to her about it. She may have simular feelings and you could masturbate together, fool around some. BUT.... if you should fuck, use birth control. If she can't get on the pill, use condoms. And make sure they are good quality; cheap ones tend to break. The last thing you need is a knocked up Sis on your hands. Your parents would freak over that. Also, make sure they do not find out, if you do do anything with her. That would not be good either, I assure you. But best bet may be just to jack off, and leave sis well enough alone. Good luck with the problem!

Incest... Bleh.

Lop your dick off?

your just into incest thats all. don't act on it though
