This weekend was eye-opening. Friend of mine spontaneously invited me over, show up to his place and there's two hot chicks naked on his couch dry humping each other. We play truth-or-dare, and the same friend has one give my other buddy a lap dance and make out with him. At this point we decided to head to the club, one sat on my lap and the other next to me. The entire ride consisted of me finger-banging one while making out with the other.

Staying on track, having seen two hot, wealthy girls basically give themselves unrestrained, when I got to the club I was iffy about trying to pursue either of them. Plus the friend who orchestrated this said he had fucked both and said I could have one if I wanted. Now my mind started considering fucking her.

Turns out the girl my friend gave me the go ahead to fuck had a friend there. A guy about the same SMV as me, but definitely more into her. He came up and immediately started mate-guarding, and at this point I was caught off-guard. While I wasn't entirely into that girl, I was intending to use her as my back-up slut for the night if things didn't work out. Being I was iffy, I immediately backed-off and went about my night elsewhere.

I had a good night, but the beta mate-guarding wound up working out for that guy. He sacrificed having fun with his bros and talking up other chicks to stick right beside and follow that girl, then take her home to fuck her. Is that a win? To me I felt it wasn't worth essentially throwing away my night to get to fuck a slut that my buddy had already plowed. Then again, let's say that wasn't the case, I don't know how I would have acted.

TL;DR

When confronted with obvious mate guarding, how would someone go about dealing with that? Increase kino with the girl, make out with her in-front of the dude? Or would you shrug it off, immediately give up on the girl, and find another? The former to me feels it would illicit a fight and require you always being around, while the latter seems that any aggressive male will push you off your female.

Really confused with this. Advice is definitely needed.
