All people of heaven Allah will purify their hearts from psychological malice, bad morals, and despicable desires.
In fact, when you meet the Hoor Al Ayn in Jannah, you wont be looking around for men :')
Allah describes them in Surah Ar-Rahman ( Surah #55 ) verse #56:
فِيهِنَّ قَاصِرَاتُ الطَّرْفِ لَمْ يَطْمِثْهُنَّ إِنسٌ قَبْلَهُمْ وَلا جَانٌّ
In them are women limiting [their] glances, untouched before them by man or jinni
And in verse #58:
كَأَنَّهُنَّ الْيَاقُوتُ وَالْمَرْجَانُ
(In beauty) they are like rubies and coral
And also in verse #72:
حُورٌ مَّقْصُورَاتٌ فِي الْخِيَامِ
Fair ones reserved in pavilions
And in Surah Al-Baqarah ( Surah #2 ) verse #25:
وَبَشِّرِ الَّذِين آمَنُواْ وَعَمِلُواْ الصَّالِحَاتِ أَنَّ لَهُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الأَنْهَارُ كُلَّمَا رُزِقُواْ مِنْهَا مِن ثَمَرَةٍ رِّزْقاً قَالُواْ هَـذَا الَّذِي رُزِقْنَا مِن قَبْلُ وَأُتُواْ بِهِ مُتَشَابِهاً وَلَهُمْ فِيهَا أَزْوَاجٌ مُّطَهَّرَةٌ وَهُمْ فِيهَا خَالِدُونَ
And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally.
Every time you gaze upon her, you see nothing but that which gladdens the heart.
I believe the homosexual feeling you have now will fade away when you get to heaven inshallah.
And Allah knows the best.
