Im straight but cant stop sucking cocks

Hey everyone, i got a reddit account just to try and talk with you all because you seem like a good community. I havent spoken to anyone about this and its tough.. So im a 20 year old straight man(At least thats how i feel) you know like i found lots of women attractive, ive had girlfriends, i love sex with girls. Ive never thought a guy looked cute or looked handsome and ive never had feelings for a guy either. BUT i cant stop thinking about sucking another guy off. It turns me on so much..Id say im a bottom (?) I want to be a good boy, suck it like a real slut, watch the guy in his eyes while hes putting his dick in my mouth. Ive done it like 5 times, i meet up with a man from a bi gay forum i often spend my time at. The men have mostly been 40+ years old and it turns me on a lot, the fact that a 40 year old family man meets up with a 20 year old just to get his dick sucked in his car by me. Im also a bit freaky, i love fantasies and role plays. One guy was acting like i was his real son and he was saying some graphic things while i sucked him, and it turned me on sooo much. Another man wanted me to bring my moms panties, when we met he took them up to his face and smelled my moms panties while her son was down and taking a big hard dick in his mouth. I feel like im letting down my mom too when i do it.At night when i go to sleep i can feel bad, or feel a bit sick in my stomach because im afraid theres something weird with me because this is not making sense, how do i not find men attractive but i still LOVE to suck their dicks? Like i LOVE it, not a little, not like "thats exciting", i REALLY love it. Then the next day when i go to the forum to find someone new, i get turned on again and want to do it. Nobody knowz anything, lm a pretty "tough" and masculine guy otherwise, but nobody knows that at night im a good boy who suck off older men in their car just because i want to have my mouth filled again.I dont want to write too much because i dont want to bore you guys. Id love to talk here in the comments about it. Anyone else feel the same way i do? Please talk to me!
