Would  you please define what you mean by a couple of things in your post?

What is "thight"?  Did you mean "tight"? 

If you did mean "tight", wouldn't she be looser with good sex play before penetration for preparation and if she is really ready and well-lubricated? 

She is not doing a horse, is she?

Second, virgins ("arn't?) aren't very good in bed the first time? 

Why not?  I hope that they are better spellers.  If you don't spot any wrongly spelled words in my answer, well, it doesn't mean I am a virgin.  I am not a virgin, not to heterosex anyway.  I have not tried everything though so I guess you could say I am a virgin in some ways.
