Penetrating Your Vagina for the First Time

I always recommend clitoral stimulation to build sexual interest before any vaginal penetration takes place if you want penetration to feel good.
Dear Dr. Betty,
I used an exercise bike about 2 months ago. The seat put a lot of pressure on my perineum, but never made any contact with the clitoral area. I experienced this shooting pain in the perineum area a few hours after I got off of it, and it occurred again on and off for a few days after. I'd only used the bike for an hour. 3 days after, I was unable to orgasm.
