Strange ..... if you're functioning normally ..... why e hack your bf still needs to looks for ONs? If he's really such a scum ... might as well look for a better guy who will respect you, right?
Another scenario might be you're still a virgin and you're worried if he can't get you, he might try on other gals?? If that is so .... drop him lor ... what have you got to lose anyway .....
Seldom guys will go to a pub and look for ONs when he already have a regular partner unless like what I mentioned in scenario 2 or he has a d*ck as long as a trunk and he can't wait to shoot it off.

You should know your partner well ... whether he can tahan the temptation depends a lot on his will to resist it and his devotion in you.
If he's drunk ... then it's too bad .... after all, it's something no one can predict in the first place. When that happens, it depends on how strong your love for each other are. If he's sorry about it and you're willing to forgive and forget; nothing's happening. If he pretend, pretend .... yah ... there might be a problem after all.
So don't think or worry too much about the after effects. Right now, he's enjoying what he's doing anyway; resticting him might make things worse ... if you really feel lousy; talk to him and see how he will react; if he's sensitive enough to your feeling, he won't blame you.
