According to Dutch Researchers, Swingers have a higher incidence of STD's then Homosexuals and Youth:

The study, published online ahead of print in the journal Sexually Transmitted Infections, found swingers were among those with the highest rates of sexually transmitted infections -- young people and gay men.
The combined rates of Chlamydia and gonorrhea were 10 percent among straight people, 14 percent among gay men, just under 5 percent in female prostitutes and 10.4 percent among swingers. Female swingers had higher infection rates than male swingers.
Fifty-five percent of all diagnoses in the those age 45 and older were in swingers, compared with 31 percent in homosexual men.
STD's have little to do with whether you stick it in the same sex or opposite sex and EVERYTHING to do with whether you practice safe sex and if you choose to sleep around with anything you can with a relaxed attitude towards safety. As one poster mentioned above, yes two gay men may take a less safe approach to sex since there is no fear of pregnancy and therefore a condom, to them, may be a second thought. That same attitude is taken by "invincible" teenagers who think pregnancy can't happen to them either. At worst, the gay males are no worse then horny heterosexual teenagers.
