Metronidazole trichomoniasis

110 million people have STD's. 50.5 million men and 59.5 million women. Roughly 1 out of every 5 people have genital herpes. The rate is more than twice that among our youth. Men, aged 20-24:are most likely to have STD's. In 2015 the rate of STD's was the highest since 1992. The most common STD's are chlamydia, gonorrhea, hepatitis B virus (HBV), genitall herpes, HIV, human papillomavirus, syphilis, and trichomoniasis. I am amazed that STD's don't appear in at least 20% of the stories here because those are the statistics associated with divorce among cheaters.

Sex, whether as part of a long-term relationship or a one-off, should always involve trust and respect. Ideally, those involved should also be aware of ALL possible consequences and act responsible (its easier to enjoy yourself when you don't have niggling little worries in the back of your mind). Before having sex, you should discuss not only (1) birth control (contraception) but also (2) STDs. Remember – some people lie - and it’s not worth risking your life and/or future happiness for a quick roll in the hay. Condoms do an excellent job of preventing both disease transmission and pregnancy. You and your partner(s) can get screened at your doctor’s office or local clinic.
For unbiased advice and information about both contraception and STDs, you can consult reliable websites from agencies such as: Health Canada, the Canadian Health Network, the Society of Obstetricians and Gynaecologist of Canada. (I don’t have enough experience with foreign resources to recommend any). If you think that your own doctor is in the pay of the pharmaceutical companies or has an agenda that does not match yours, consider changing doctors.
(1) There are other forms of birth control that you might wish to investigate, including IUDs (intra-uterine device, AKA “coil”). There is a newer one that contains a very small amount of hormone but most IUDs don't. Once inserted, it should have few side effects - if any - and can be worn for several years. They have a respectable contraceptive rate (99% effective) and I don't believe that they have any long-term fertility effects. The only down-side that I know of is that they may raise your susceptibility to some STDs but if you and your partner(s) get tested and take precautions...
(2) What about STDs (sexually transmitted diseases)??? Do not underestimate them. Sure, some can be cured, but many cannot and only the symptoms can be managed. Syphilis, gonorrhea, chlamydia, HIV & AIDS, genital herpes, Human Papilloma virus (HPV), Hepatitis B Virus, Trichomoniasis. NOTE: HPV infection can lead to cervical cancer.
