I think it shows responsibility if both sides have it. The guy definitely should have one on him if he intends to use it. As for the female, if she knows its going to go down, it wouldn't hurt to have her own supply. It doesn't mean shes a ho for having them. It shows that she knows her own life is worth something. Plus, you never know. Fellas, that ol' trojan you had in your wallet might've expired by now. House Party anyone?
I think a woman should have respect for herself and value her life. You should always be prepared, sometimes you don't know when you will be intimate with someone, so it is always best to be prepared. For instance you might see an old boyfriend by coincidence and you both might want to rekindle an old flame or just get busy. The point is always be prepared and look out for your own best interest.
