(GIRLS_)this is sorta embarassing to ask, but please take me seriously..am i loose or is my bf small?

Sometimes there is a psychological connection with sex. I have been with guys where it was really hard for them to put it in even though they were not that big. Perhaps you were not that relaxed with your first bf. It could also be an issue with lubrication. If you have more lubrication this time then it will go in easier and you may feel looser. That is not a bad thing. It is generally an indicator that you are excited and really like the guy. You are probably not loose, but if you feel self conscious about it you can do kegel exercises to tighten your vagina. This is generally not needed unless you have had a baby. Another option is to use a vibrator for clitoral stimulation while you are having sex. You vagina will contract as you get close to orgasm making sex feel better. Hope this helps.
