Im a male and my partner is also a male and the situation here is " can i drink his semen"? is this dangerous for me?

No: When a woman (or man) swallows semen or sperm, her body just treats it as food (a small snack). It has no effect on her body, so if her shows some changes, it is merely by coincidence. However, life is never that simple. During the process of obtaining that semen, she might also obtain various viruses, bacteria, ureaplasma, etc..., from he who is the source of the semen. So, swallower beware.
