I'm in love with him. We're dating. But... We've been together a few times, and sometimes it works, sometimes it doesn't. It worked out on four dates. Or it can't start at all, or when it starts, it ends very quickly. He thinks it's all right. I don't want to crush his self-esteem, but how do I tell him he's supposed to be taking some pills? How am I going to behave at all? What am I going to tell him? And I answer "it was a little bit," I dare not say more. I don't want to lose him, but for things to go, he has to drink something or visit a sexologist. But how do I tell him? Give me some advice, please.
