Thank you for your question. there are two different aspects to your question. first is related to your penis being bent. This can be normal in some cases but it is better to get it checked if you have noticed this recently. There are no medicines to increase penis size. As long as it is 2 inches or more it is sufficient since the vagina is most sensitive in the outer 2 inches. The second aspect is about lasting longer and smoking. Smoking will most likely cause harm in the Kong term and should be avoided. You can practice delaying ejaculation by reading about masturbatory exercises in ' managing premature ejaculation' by Metz and Mc Carthy. Alternatively consult a sex therapist or psychiatrist for help. best wishes
