This type of thing used to happen to me in middle/high school, girls with BF's would send me pictures and videos and stuff and I felt terrible because I knew they had boyfriends, but because I also enjoyed it I didn't tell them to stop lol

Back then this would be a no brainer, just get the pics and enjoy, but now I wouldn't specifically ask for them if she has a BF, that's messed up(Try thinking about your GF doing that)

Now if she just sends some randomly...well there is really nothing you can do about that lol

There are two options here:

Moral high ground - Decline out of respect for the dude and relationships.

Justified Personal Gain - She'll likely be unfaithful anyway, why not profit from an inevitability?





Personally, I'd take the high ground.




...but then again, I haven't seen her

Depends.

If you don't care about dating her in the future, go ahead.

If her boyfriend is your friend as well, base it on the value you put in your friendship.

If you don't know the guy, don't care for their 'ship, and she's hott, go right ahead.

The only morality is what you place upon it. If you're doubting doing it now, then you probably shouldn't do it. If your doubt is less than your desire, refer to my above statements to figure it out.

Look at it this way...

How would you feel if your girlfriend was sending pics of herself to her Ex?

I know in the heat of the moment you'd thing is fun and games... But Karma gets you eventually.

Be a man and tell her no, because you respect her and her relationship.
Whether that is true or not. Sometimes you as a man have to have some standards and not sink into more drama.. This is why girls act the way they do..

But what do I know...

@toxik

I mostly agree, but instead I would just be straight up and say something like "You realize this goes against what your doing with the other guy? That it could screw that up?" As long as you've done that part, I don't think you would be doing anything wrong. But morality is subjective, the best you can do for yourself is think about it critically. Don't be afraid of making mistakes, you learn more that way.
