We have almost gotten to last base and she is still claiming V

Good day house, please I need help from you all. I beg you not to see my post as a nonsense post because this is very important for my manhood. The thing is that I have been dating this girl for 7 months now after chasing her for about a year, I finally got her and we started dating then she started to give me the I am a Vir.in story which even though it was annoying, I had already fallen deeply for her so nothing was going to make me leave her just because she said she was a vir.in. 3 months into the relation, she felt very comfortable with me and she started coming over to my place to spend the night. The first time she came, I let her sleep on the bed while I took the couch. In the middle of the night, she woke up and came to where I was sleeping to tell me to join her inside the room so since then I started sleeping with her on the bed. Like that o, we graduated from just kissing, to sucking of boobs, then small time, we graduated to giving each other good head. Every time I give her head like this, she is always shouting and asking me not to stop. Then after that she would start putting my thing into her vag.na but she would still wear her pant o, at times, I remove the pant small to just put only the tip of my thing inside. We have been doing this now for almost 4 months and I am beginning to get tired of tasting food that I will not eat, it's just pure torture because me I don't understand the meaning of this kind of virgin that has almost gotten to last base but keeps holding back. Ii don't even trust that she hasn't made love to any man before. Now my problem is how to tell her that I am tired of tasting what I can't eat before I force my way in one day. Also will it be called r.pe if I deep it all in even if tries to  hold back after she must have used her hand to put my thing there in the first place. Please I need serious advice.
