Condoms do not protect you from everything!
Just because you think your being safe does not make it fact.  

 
The only safe sex is masturbation!
I am not one to promote abstinence but it's the only 100% safe option.  

 
That being said its up to yourself to protect you!
Many a time guys ask "c'mon I'm clean" without asking me about my sexual health. It's sad. Of course I'm safe and clean but the comete lack of regard for the fact that it takes only one person to put you at risk... Sad.
