some girls vagina are too tight. tell me some lubricant's name what I can use in first time sex.
The best lubricant is the girl's natural sex juice. It sounds like you are entering her too soon. The age old remedy is foreplay: kissing, fingering her vagina lips, massaging her mound etc. till she's aroused. That gets her vagina open and lubed with her juice. And it's fun! If you still need a lube use KY Jelly: it's made just for that. Let her smear it over your erect penis!
