Recently like to.days ago my boyfriend left his social website open I had looked through the messages and he been talking transgenders and had a transgender suck his penis... that's what it said in the message... I asked was he gay or bisexual and he replied with answers like hell naw and stop asking me that you irritating me... help me please

Well, he's either lying to you, in which case what's the point of the relationship?

Or--he's cheating on you, so what's the point of the relationship?

Either way, you don't trust him, so you may as well break up with him.

PS--get tested for STDs

Transgender/gay/bi/another girl... isn't important -- he's lying and cheating (or intending to cheat)...
His attitude towards you shows a lot of disrespect - THAT is cause for reevaluating the relationship. If he's trying to hook up with other people on the internet he's not into you.
