I found this wonderful site with useful information

We hear stories of domestic violence every day, but rarely do we imagine abuse between two men or two women. However, gays and lesbians are susceptible to domestic violence just as any other individual.
So, why do we hear so little about domestic violence between gays and lesbians and why are so few cases reported?
First off, it's difficult to determine which partner is the victim (unlike heterosexual couples where the woman is most often the victim).
Many gay men hesitate to report abuse, fearing exposure of their sexuality.
There are very few abuse centers that provide services for lgbt individuals. There are even fewer centers solely dedicated to gay and lesbian victims.
Because majority of support groups are comprised of heterosexuals, gays feel they must hide their sexuality or come out to the support group.
Many gay couples share friends, so the victim may be afraid of losing the support he finds in his partner and mutual friends.
Victims of abuse should focus on their safety and not the fear of being "outed" or losing existing support systems.
What are the different types of abuse?
Not many people realize that there are many types of abuse. Read the different forms below:
Physical abuse
Hitting, beating, choking, slapping, pushing, kicking, biting, etc.
Abandoning a partner or holding a partner down by force
Intimidating a partner, abusing pets, stealing or selling partner's possessions
Use or threats with a weapon of any kind
