They look like men, but how do you know they're not eunuchs or asexual? You don't of course. You just assume because the bible calls them men, which they are not, that they have wieners.
Speaking of assumptions, let me address your assumption.
Did Jesus have a wiener/penis in his earthly body?
Yes, he did. We know this of a certainty because he was circumcised when he was eight days old.
Does Jesus still have a wiener/penis in his glorified body?
It seems to me that he does...unless you have some scriptural evidence which suggests that he has since become a eunuch or asexual. You don't have any such evidence, do you? If you think that you do, then post the scriptures which support that hypothesis.
I am a man, and the last time that I checked, I had a wiener/penis. Hold on a second. Yep, I still have one.
If I attain to the resurrection of the just, will I have a wiener/penis in my glorified body?
Phl 3:20
For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:
Phl 3:21
Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
The presently vile bodies of Christians will be fashioned like Jesus' glorious body in the resurrection of the just. Again, does Jesus, as a male, currently have a wiener/penis? I believe that he still does. If you believe that you can prove otherwise, then post the scriptures which prove it. If Jesus, as a male, still has a wiener/penis in his glorified body, then I fully expect that all males who are saved will still have wieners/penises in their glorified bodies as well. Is that somewhat of an assumption on my part? Sure, it is, but at least it has credence in scripture. What you fail to recognize and admit is that your oft-repeated claim about angels not having wieners/penises is an assumption on your part. Does you assumption have biblical credence? You think that it does, but it is not nearly as credible as you personally and presently believe it to be.
As others here have already pointed out to you, whenever gender is stated in relation to angelic beings, they are either fully male or, in the case of the living creatures, at least one of their faces is the face of a man. Furthermore, other descriptions which pertain to males, like princes and kings, are used in relation to angels in scripture. Further still, angels make up the heavenly host or army, and, in scripture, it is the males who God sends out to war or battle, so that is another indicator that at least many angels are male.
With this information before us, it is perfectly rational to consider that male angels have wieners/penises in heaven, just like Jesus, a male, and the male saints seemingly do or will.
Is Jesus having sexual relations in heaven? No, he is not, but this does not necessarily mean that he does not have a wiener/penis.
Are any males saints having sexual relations in heaven? No, they are not, but this does not necessarily mean that they don't have wieners/penises.
Are any angels having sexual relations in heaven? No, they are not, but this does not necessarily mean that they don't have wieners/penises.
Does the Bible at least imply that a specific subset of angels WHO LEFT HEAVEN had sexual relations with women HERE ON EARTH? Yes, it does.
Jde 1:6
And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
Jde 1:7
Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
I am still waiting for you to tell me who these angels are who sinned (2 Pet. 2:4) after not keeping their first estate, or after leaving their own habitation, or after LEAVING HEAVEN in order to give themselves to fornication, and in order to go after strange flesh, IN LIKE MANNER or EVEN AS the sinful men of Sodom did.
