Hello, I Am A Transgender Male And I Have Been

Hello, I am a transgender male and I have been having a lot of discomfort in my vaginal area. I work and I sweat a lot, as well as walk a lot, and I figured that's why I am itchy and moist sometimes down there. I also have a burning sensation but I figured that was from my thighs rubbing together. I have had one sexual partner for 5 years and she is a female. We have sex but with a dildo and I usually just do it to her not the other way around. Recently, as in a couple of days ago, I had sex for the first time with a male. It was protected and he did not ejaculate inside of me. That was the only time I have ever had sex with a male. I started having greenish yellow discharge about 3 days after the sex, and when I smell it on the toilet paper, it smells like mucus as if I blew my nose and had a cold. Can you tell me how can I fix this and what the problem may be? I had safe sex and only done it one time.
