Talking about sexually transmitted diseases, safer sex and all that junk isn’t fun, but it’s important to do before having sex with someone new. Safer sex may be serious, but the way you discuss it doesn’t have to be.
Try using some funny condom slogans to get your point across without totally killing the mood:
Keep calm & (female) condom on
No Glove, No Love
1 + 1 = 3 if you don’t use a condom or other type of contraception
Don’t be silly, protect your willie
Be Wise, Condomise.
If she’s eager, protect her beaver
Don’t be a fool, cover that tool
Protect the fish then dip it in the dish
Plug the funnel then enter the tunnel
Don’t be a joker, wrap your poker
A condom a day keeps the pregnancy away
