First of all, welcome to MS. If you would like, you could post a brief introduction of yourself in the Introduction section, saying who you are and what lead you here to MaleSurvivor. It would give the guys here an idea of who you are, and give them the chance to welcome you.
Same Sex Attraction (SSA) is a common symptom of being sexually abused. You are not alone in having these feelings. Many straight men here have also come forward with this issue. My suggestion would be to search for "SSA" on this site and see what you can learn from others' stories.
Good luck. And welcome home. You are among brothers.
Your new friend,
