The definiton of homosexual is when an individual prefers sexual activity with the same sex partner. Rape don't count. You know that.
With the exception of the duties of my profession, nope, never been to prison.
I never said it did. Prison rape occurs, depending on the prison, at a rate of 14-25% of the population.
A 1982 study of a medium-security prison in California found that 14 percent of inmates had been forced into oral or anal sex. If that figure applies to all jails and penal institutions, about one million males are raped behind bars each year. Wooden, Wayne S., and Parker, Jay. Men Behind Bars. New York: Plenum Press, 1982. The one million figure is based on the fact that about 8.6million males pass through jails and prisons each year, according to the Sourcebook of Criminal Justice Statistics, 1990, Tables 6.33, 6.63, 6.89, and 6.90.
In 1996, Cindy Struckman-Johnson of the University of South Dakota published a survey of the Nebraska prison system showing that almost 1 in 4 inmates had been "pressured or forced to have sexual contact against [their] will."Struckman-Johnson, Cindy, Ph.D., and Struckman-Johnson, David, Ph.D. "Men Pressured and Forced Into Sexual Experience." Archives of Sexual Behavior, Vol. 23, No. 1 (1994), pp 93-114.
Consensual homosexuality on the other hand in prison runs at a rate between 41-70% and I’ve read as high as 78% in the Florida prison systems though I can’t put a finger on that cite at the moment.
In prisons, many males are involved in homosexual sex. Dr. Frank Rundle who …"believes that it's almost universal," involving "almost everybody at least sometime." Another professional gives a 70 percent estimate Rideau, W. and Sinclair, J (1982). Prison: The Sexual Jungle. in Scacco, Jr., Anthony M., Ed… 3-29.
Questionnaire responses from 13- to 17-year-old girls in four all-female and three coed institutions were used to determine rates and causes of institutional homosexuality. Rates were as high in coed as in single-sexed institutions. The overall rates of homosexuality for all seven institutions were 14% for "going with or being married" to another girl, 10% for passionately kissing, 10% for writing love letters, and 7% for having sex, beyond hugging and kissing, with another girl. The data suggest that previous homosexuality, often experienced in other correctional programs, explains much of the variance in institutional homosexuality.
