Because... Is that exchange of saliva really worth it when you look at the benefit at the time vs. the costs of contacting meningitus?

Is the licking a penis so appealling when you might contract HPV (and end up with genital warts and / or cervical cancer) and trying to explain that to a life partner / long term relationship / casual relationship even.

Part of the emotional investment... Is in accepting the risk, I think. To have unprotected sex with someone is a significant emotional investment... Because... You are partly risking your life. I mean... If they are infected with HIV then they could kill.

I'm all for free love... But that was an ideal of the 60's.

Medical science has progressed since then.

For better or worse.

(Don't get me wrong - I've engaged in unsafe sex practices that I'm really not proud of. Where I'm really not proud of them, however, is with respect to what I may or may not be carrying that may or may not put my current partner - who I may well love - at risk. If I ended up being HIV positive... Then we would be doomed to a life of condoms for ever... If I ended up being a carrier for genital warts and he wasn't... Well... How much does he love me to have sex with me without a condom? Do you get the picture?????)
