Most of the studies listed below rely on self-report data, which poses challenges to researchers inquiring into sensitive subject matter.
More importantly, the studies tend to pose two sets of questions.
Openly LGBT people remain a demographic minority in most places.
In areas that historically are not known for having (or being friendly to) LGBT people who do not remain closeted, a "first" can make it easier for other openly LGBT persons to enter the field or for those who are closeted to come out.
Many lesbians have had sex with men in the past and may be carrying STDs from previous male partners without being aware of it.
There have also been reports of HIV and syphilis being transmitted between women.
The results found that 8.6% of women and 10.1% of men had at one point in their life experienced some form of homosexuality.
