Erection problem. Medication on this.

Erectile problem and early ejaculation :  I'm 25 and I had hair fall issues. So I was prescribed with Finax tablet for 4 months on alternative days. I had better results. After the fourth month I was prescribed with Keraglo men and H vit Forte tablets. Now it's almost 7 months. But I'm not keeping well with my sexual life. It is clear that it's because of Finax. Last year before the commencement of the treatment, I had good erection. now even if I have erection, I'm ejaculation rate is quite early. max time 3 mins. can you prescribe any medication on this. I'm not used to have intercourse on daily basis. I'll be having it like once or twice in a month. Can anyone suggest me tablet for this. I've also heard Tadalis 10mg helps is in this issue. Please advise me if I can consume it. If so please let me know the usage. Thanks in advance.
