HELP BOYFRIENDS PENIS IS SMALL

Okay , I love my boyfriend so much but his penis isn’t nearly as large as my previous “lovers” the sex is so bad. To make it worse he has to pop pills (blue pill) to get excited and in the mood. We’ve been on and off for about 2 years and it’s so hard trying not to step out in the relationship. In a previous argument he claimed he wasn’t attracted to me. What should I do ??
