Vomitting on taking sex pills. Also.

Erection is not harder and also premature ejaculation. 12 years ago had a treatment and got very good result on using Deaxid-25 mg/daxid 50 mg and thab sieldanafil tablets, So i have used a lot. But whenever i take these tablet i feel that its stuck in my upper chest and feeling vomiting all time, so vomiting occurs when i take some food otherwise its suck up from inside. Also when i do sexual activity sometimes erection goes, Also i feel piss at a same time. when i get erection harder i feel pissing also. Also have low energy as after discharge i feel very low amd cannot attempt second time. my blood pressure is generally on lower side, acidity problem also with me So please advise for having longer and harder erection Pills which i can take and dont feel vomiting Pissing problem, i do lot in night, Not feel empty after pissing and not have much pressure during pissing and feeeling very sensitive on tip.
