● Stick to “What’s mine is mine.” Don’t share vibrators or other sex toys with your partner.
● Get regular checkups. If you or your partner have more than one sexual partner or if you suspect that your partner has had more than one partner, you should have an STD checkup every six months, or after an act of unprotected sex that may have caused an STD. Remember that some STDs may still test as being negative within the first few days/weeks.
● Use common sense. Look closely at your partner for any signs of STDs -- a rash, sore, any unusual redness or discharge. If you see anything that concerns you, abstain from sex.
