This wasn't worded well. Please skip to edit 2

Why do "straight" men check you out look you up and down but then when you approach or say something to them they act like their not interested. Not staring as in a gawking or hateful way like legitimately sexually look at you. It's so annoying and frustrating. Either approach me be comfortable with me approaching you or stop looking at me! I'm a curvy guy so I have breast and a huge ass and I wear panties. I don't have body hair. I'm in the shelter so Ive shared several rooms with several guys and most of them are always staring me down when I'm putting on lotion or walking around the room. They literally love what they see but even a basic conversation seems to be off the table for them as if they'll catch my gay disease. But if a woman or straight guy tries to speak with them suddenly their the most social person in the world. Please help me understand

Edit*** multiple comments are saying im delusional. Ok. Noted. Thanks for the input. Gotta say I'm really surprised with the responses I got. I usually have a policy that everyone can't say the same thing and be wrong but I gotta say I think all of you are wrong lmao. Agree to disagree

Edit 2*** The point I tried and clearly failed to make is this; "It's frustrating that I can't be talked to or seen as a normal human being by ALL the people around me. Not just the men. When it comes to the men though they will refuse social interactions with me but will aggressively sexualize me instead. Why am I not good enough for a 'good morning how are you?' when everyone else is. But I am good enough to be looked at all day long every chance you get or to be sexually approached in inappropriate ways. When I said the part about being comfortable with approaching me or me approaching them I meant in a conversational way not in a hookup sexual way."
