It's not just the STDs but cervical cancer, breast cancer etc... There are so many other reasons to go to an OBGYN. Even things like HPV...while they may not show symptoms in everyone (since there are a bajillion strains) it can still cause serious problems. I strongly urge you to go. Women fought so hard for equal rights to health care and you should take advantage of it. It's for your, and your partner's, health.
