A straight guy's curiosity

Hello, people of AJ! I've been torn about this for the longest time and today I had a talk with my gay friend about it. I need to know what you guys think and, if you can, give out any advices.

It all started when I first encountered the world of online hookups, especially the r4r subreddit. I am a very straight guy (yes, this sounds fake but I really am straight) and never in my life would I let a gender besides a female do anything to my body. I've always imagined doing it with a female and never with a gender outside of that (yes, I have no experience yet).

But, however, after spending some time in that subreddit and here in AlasJuicy, I've come to develop a wider net when it comes to sexual things. I started looking at gays less repulsively (in terms of sexual things ah, I'm not homophobic...) and the same goes for trans, femboys, twinks, and etc.. I've slowly became conditioned and shown to media about the lgbtq+ and their sexual life.

Now, here comes the dilemma. I told my friend that I would let a guy suck me off, but I wouldn't return the favor to him. I also said that I'm willing to receive a handjob from a feminine looking guy (twinks, femboys). This all came from the context of if pleasure would be better if it came from oneself or from another. After hearing my answers, he said that I was gay/bisexual and I should consider exploring that side of me. AGAIN, I AM IN NO WAY ANY SHAPE OF FORM SOMETHING OTHER THAN STRAIGHT. I like my women, but I'd let a guy suck me off.

So here it is, does me letting a guy suck me off mean anything? is it normal or is it gay? Like I said, for me its a fairly normal thought... but what do you guys think?

Thank you for all the responses that will be sent! I will appreciate any comments and queries!
