Age no bar in active sex life

Up to what age can a healthy man have an active sex life? I fantasise about having sex with goodlooking women. Is it normal to feel so?

As long as a man is healthy and physically fit, there is no age constraint for an active sex life. Fantasising is a normal and common behavioural trait. But  make sure that you limit it to fantasy levels and do not try to act it out.

I am a 17-year-old girl. I went on a date and my boyfriend kissed me on my lips. Does smooching cause pregnancy? Are there chances of getting infected by STIs?

Smooching cannot cause pregnancy. For a pregnancy to occur, a man’s semen has to be deposited in the woman’s vagina. Theoretically speaking, lip-to-lip kissing can produce sexually transmitted infection. If one of the partners has an active ulcer or a raw area teeming with disease producing organisms in the lip and the other partner has a broken/chaffed/abraded lip, then the infection can be transferred to the uninfected person. But in real-life situations, this occurrence is rare.
